Blackberry — not repaired phone under warranty

Address:

Bangalore, Karnataka

i would like to take legal action against BlackBerry as they've cheated a loyal customer. I bought BlackBerry 8520 on 06 may 2011. It's just been 4 months and the phone got problem about track ball not working,i had approached to the service center on 06 sep 2011 in dehradun,work order no DUN/BB/11/00317,after 7 days they said that water drops was there so it is beyond repairable,i was astonished even a drop of water hasn't gone in my phone.If there was water drops it's warranty period finishes i got serviced my nokia phones so many times if liquid damage is there only warranty lapes but they service the phone, so i was ready to pay but they said it's not repairable.I questioned about water drops but neither they satisfied me nor agreed to service that on payment,i came to bangalore and again approached to black berry service center and after seven days i got the same response,this was the second time i was harrsed by blackberry service center .Again when i went to service center in dehradun they said it is not repairable and you pay the amout of same handset blackberry 8520 and they will give me a new same handset and will keep the unrepairable one with themself, it was enough for me third time i was harrsed by blackberry service center,finally i went for local repair shop and within 7 days i got my track ball problem solved then I realises that if my phone warranty was over service center could have repaired it in very first time. I wasted so much money and harresed by black berry services.In that regard i want retribution money from balck berry.I hope this forum will help.Advice me to file a case.
