HTC India — Repair delay of mobile phone

Address:

Lucknow, Uttar Pradesh, 226006

My name is Dev Jyoti, I gave my HTC Desire 826 model at TVS ELECTRONICS Limited on 6 June, 2016 as my phone was registering some problems with the usb connectivity.On submission I was promised that the repair would be done within 2-3 days or by the end of the week at the latest.As of now it has been almost a month and I have not yet received my phone and what is more harassing is that they have stopped attending to my calls.Earlier they used to delay the probable date of giving the phone but now they have stopped receiving the calls altogether.
