As a follow up for this case, I contacted Dell thrice today. Each time the technical support person told me that the case is now handled by the escalation team and they can't do anything. But they told me that they have sent reminders to the escalation team and I will get a call before end of the day since they are still working on the issue.
But I guess the escalation team was just trying to buy time until end of the day. Because after that I cannot call back on the Dell's technical support no. Also, I received a call from the technical support department finally at 6 PM. I cross checked with him and he said that he is NOT from the escalation team and he is just from the technical support team. It is very funny that when I had called up 3 times, the tech support team people said that they cannot handle this case any more. But instead of getting a callback from the escalation team, I got a callback from the tech support team person, which again had nothing good to tell me. He said that if the part replacement does not work one more time, we can raise a whole unit replacement request again. But when I told him to send this in an email to me, he was not ready to do that. The call also got disconnected in the middle of the conversation and he never called back!
I will keep writing about my interaction with Dell and expose the various ways they use to find excuses and delays!

Well, Dell seems to be reaching the heights of Quality lapse and logistics failure.
On 30th December 2010, a service call was scheduled to make one more attempt to fix the issues. The cal was even worse. AS mentioned before, the motherboard was with even more problems. The CPU fan was not of correct model and was not suited for this laptop. Then again I had to contact the Dell's escalation team and had a talk with the escalation team person. Frankly, the conversation was highly unpleasant. Then again, since i had no other option, I agreed for one more service call. This call was scheduled for 4th January 2011. Once again a replacement motherboard and CPU fan was sent. Unfortunately, the CPU fan (with attached heatsink) had a bent rod and the engineer to had to manually bend the rod to align it with the screws. But the problem did not stop there. The CPU fan is actually faulty, it simply does not work and the laptop gets extremely hot and shuts down. The CPU test of Dell diagnostics also forces the laptop to shutdown abruptly and at that time the laptop base is extremely hot.

Once more Dell failed to give service. The service was scheduled for 10th January 2011. Three parts were supposed to come to my place: Fan & HeatSink, Thermal Paste and Motherboard. Out of this the main part was Fan because that was not working (refer to my earlier post in this thread). But Dell did not send Fan and Heatsink!
So, I had to call up Dell again. And again Mr. Manmeet Bhatia from the escalation team promised to get the part delivered by 14th January 2011. However, when I contacted the logistics team today, Mr. Sudheendra told that the parts won't come until 3 more days!

Here is the email from the escalation team:

************************************************** *****************************
"Hi Ishan,

We are following your case and trying our best to ensure that the same is closed at the earliest, the part(heat sink and fan ) would reach you on 14th of January for the service to happen, secondly the other day I spoke to you, I explained to you that extension of warranty as compensation is not at all possible, our main focus at the current moment is to get your system fixed.


Thanks & Regards,

As you can see in the signature, Mr. Kamal Maggo is the manager. I have even sent him email. But that has also not helped!

As you can see the series of posts that I have made about the poor quality of Dell's service (forget poor quality, this is a failure of service and not one but multiple instances of service failure for a single case (#5774825)), I am asking concerned people (admin, various moderators and advocates) at the consumer forum that is it even worth following up the case with Dell anymore? And should I go ahead and take a legal action against them? Kindly advice me on the same.

Finally, I was put in touch with the "Senior escalation team". I got to talk to Harish Marappa, who listened to the entire case patiently. He got the problem resolved and also as a goodwill gesture promised to extend the warranty by an year.
It really boils down to the fact that you need to find (or be lucky to get in touch with) the correct person! Anyways, my laptop is now working fine and so I did not want this complain to be hanging around unnecessarily.

My Service Tag number ( 659T2N1 ), I have been trying reach out to Dell Tech support as my reliance net connect data card is not getting installed in my laptop, where as it works fine in other laptop, As I was very much clear that this is an issue with the laptop while installing I have been calling DELL tech support, every time it gets connected to reception and after giving the service tag number, it gets connected to tech support team where no one respond the call, rather they just disconnect the call in between or the call will be black where no one talk.... numbers I tried to reach are 1800 425 4051 and 1800 425 8045.

Do we have any escalation contact number who can help me in getting the response.
