Lenovo — Lenovo-vibe-k4 note

Address:

Patna, Bihar

I purchased a Lenovo-VIBE-K4 NOTE mobile set from dehradun on 02.03.2016. But for last 15 days there was some problem in the set. The charger point was not responding and there was problem in charging of the set. Apart from that even on-off button was also troubling.
I contacted the service center of Lenovo at Patna and left the set with them. After 3 days I was informed that the Mother Board of the set has got corrupted and I have to pay Rs. 7500.00 for repairing of the same.
My mobile is under warranty period and hence i took the set back from the service center. And now there is another problem, I am unable to listen to the voice of callers.
Details of set - model - A7010a48
IMEI1-[protected]
IMEI2-[protected]

Kindly help in the matter.
