I had given my Sony Ericsson handset W890i for repair to the Sony Ericsson authorized service center in Sec-18. Initially it had the problem that the charging point and the handsfree point(common in Sony phones) was working intermittently. The service center registered my case and gave me a job sheet (Work order no. SE31002114645). I got my cell back after 2 days on July 14th. I did not have my handsfree at that time to test, but the phone was charging fine.
Immediately after 2 days, it started giving further problems where the headset sign was showing even without the headset being connected to the phone. This meant that even if I had to attend to a call, I would have to do it through the handsfree, otherwise it would not work.
I went to Sony Service center again and this time they said that they would have to send it to their head office in New Delhi and gave me another job sheet (Work order no. SE31002115337). After almost a month of follow up, these people called me up and said that your set is not repairable because it has been returned from our head office. I rang Sony Ericsson Customer care and they said if you let us talk to Service Center, we would ask them to repair it. I reached their Service Center and called up Customer care. The gentlemen from Customer care tried to help but the Service Center people were too adamant. Finally, when I checked my phone while taking it from Service Center, I found out that it had a message stating "Insert Correct SIM". I tried it with multiple SIM cards and it did not work. I showed this problem to the Service Center people. They took my phone back with the same work order no. (SE31002115337). Those people kept my phone for 2 more days and finally called me up and asked whether I have purchased this phone from outside India? I told them that this phone was purchased from authorized Sony Ericsson center in Gurgaon (DT City Center). To which those people added that whoever I have purchased this phone from, has purchased it from out of India and now it has got country lock and thus is not repairable. The lady further added that this can only be done from the “grey market”, so there is nothing much that they can do and asked me to collect my cell phone.

The biggest damage is that I gave my Sony phone in at least a working condition to Sony Ericsson authorized service center and now it is completely unusable. I had purchased this phone for around Rs. 15000.
