HTC — Very bad service from a brand like htc

Address:

Hyderabad, Andhra Pradesh, 500027

Hello,
To whome so ever it may concern,

I am writing this mail with reference to ticket no-[protected].

My father - had bought a new htc - desire 8203 (Dual sim)
About an year ago, date - 3rd may 2015, from a outlet in himayathnagar, hyderabad

After about 3 months o[censored]sing the phone/device, he has been facing a lot of technical and software issues with the phone, major issues being - device used to switch off randomly and then turn back on in about 8 - 12 hours,
Most of the times he had to miss a lot of important calls due to this glitch in a device that come from such a reputed company like your -htc

We have been visiting the htc repair/service center almost every month with the same problem,
Its been 5 months since the phone has been acing very strange and everytime we take it to the service center, we are told that its a hardware problem and can be solved, once the device is back, after about 2-3 days we face the same problem.

This is very unprofessional service coming from a brand like htc.
Please make sure that this problem is solved for once and we get the device replaced!

I hope i receive a reply as soon as possible, because this has been a pain in the butt for us from about 7 months.

As in for now our device is with the service center and they said they are working on the 100% check up and hardware. But i have lost trust in your system, plz make sure that the device is replaced as soon as possible so that my father (Owner of the device) can smoothly continue with his daily communications.

Thank you
