HTC India — htc desire 728 handset mic problem

Address:

422009

We have given this handset for repairing on 18th august with ticket no.[protected] (Ime no.[protected]), so far they could not repair it, they are not sure when they will be able to repair it. We have made many calls at their toll free no. But of no use, finally we have asked them to return the set without repair even that is not happening. They are not responding properly we are facing difficulties as being a 4g mobile we have changed the sim accordingly now those sims are not working in other phones.
