Address:

Chandigarh, Chandigarh, 160047

Dear sir
This is sunil gandhi from chandigarh,
I purchased htc 626g+ dual sim from anmol telecom, sec 22, chandigarh on dated 16 sep 2015.
After purchase there was a big hanging problem in the device which was showed to your service center tvs electronics ltd. Chandigarh on dated, they updated the software and given me the .
Again after few days it gives the same problem . Which was again given to your support centre . They again repaired it and given it to me
Now again there was same pathetic problem and i given it to same service centre for repair .
Now when i call up them and want to know the status . Some ravi was there who didnt talked me well and said that your ph is having some internal damage so it is out of warranty now.
I requested him to update the software only not to do anything else.
He was agree to update the software but after few seconds he denied to do anything and talked rudely with me .
I told him to provide the contact number from him he again mistalked and said manager is on leave and i will not give his number .
This is pathetic on htc's employees part that they are talking to the customers in such ridiculous way .
I am reputed officer in mohali chandigarh and working with punjab police .Grievance cell but he insulted me .
I need justice other wise i ll sue in the court .
