I bought a HTC 516 mobile on 17th-Oct-14 and the touch panel of this phone stopped wrking on 20th-July-15.As it was under warrenty I gave this phone to service center on HTC. When I followed up with HTC they say I will have to pay 8000 Rs for repair cost and gave me a quotation. When i checked the quotation was not of my phone, the IMEI number on quotation is not mine but name on quotation is mine. WHen I complaint this to HTC they said sorry and said will reply me back but now every week I have to follow up and still no reponse is there from HTC. I want to teach these people a lesson, so please suggest what should I do.
