[Resolved]  Samsung Indian Pvt Lmt — Poor Performance/Usability/Bad Quality

Address:

Dehradun, Uttarakhand

I had bought Samsung Galaxy 5 mobile handset model no-GT-I5503 on 10th September 2010 from Matta Mobile shop in dehradun. From the very next month while using the handset i started facing problems with it.It started getting automatically sitched off and on randomly at any instant while talking or using the phone and also very often started hanging.
I had complained to the samsung service centre located near clock tower here in dehradun three times but still facing the problem which is very irritating while receiving urgent and important calls or usability.They aren't able to resolve the problem and making excuses and also making me to run to them meaninglessly.
so please do help me.
The mobile set costed me 9300 rupees which is expensive one and i am very much frustated now.
i want either a new handset or my whole money back as soon as possible.
