Ludhiana, Punjab

My name is aatish i am having htc desire 700 mobile.And i have bought it to submit it all the time to htc service center yes i have submitted it at service center 3 times in 2 month after that the problem is not resolved.Evn i have done all the thing call to customer support wrote on facebook. Did all the things.Problem is still not solved. One more interesting thing there service center landline no is always busy they just put the receiver off.One more interesting thing they told me not to install apps in smart phone rather then solving hardware issue.If customer have bought smart phone then he wll obviosly install apps .Can i have some solution.?
