Tata Docomo — Tata walky

Gorakhpur, Uttar Pradesh, 273001

I am using tata walky no-[protected] for last many years. the bill payments were also very regular. but since last three/four months the walky is not working properly. there is problem in charging as well as in audio also. despite repeated complaint at your local outlet and toll free number i didn't get any responce. i had already deposited two or three bills without a single call made from it.
This is really not expected from brand tata.
You are requested to kindly look into the matter and resolve it at your earliest.
