I have also faced the same problem with Eureka Force. I bought Aqua Guard from them. They also asked for contract for 1 year (paid Rs.2000 for that) and till that time if any problem occurs they will repair it for free of cost. Now there is some problem and we have called the customer care for more than 15 times and there is no response. They are asking for Rs.2000 for repairing it. It's not worst calling Aqua Guard worst service, because they are not providing ANY SERVICE as such.
