Vu Televisions — Poor Service

Address:

G-501, Eden Gardens, Rewari : 123401

Few days back we've repaired VU TV from VU authorized service guy after logging the complaint via website at Rewari, Haryana.
The service guy, Mr. Sunil Sharma ([protected], [protected], [protected]) along with his son Yash Verma took Rs. 3, 500 from my family in name of replacing the TV screen but not given the warranty card even after repeated requests.
Anyway, the TV was working after repairing for few days. Last week, the same problem occurred and we have requested them repeatedly to attained the complaint but they are not coming.
TV serials are the only entertainment for my old mother. More than a week she isn't able to watch them.
Please help
