Kohinoor Televideo — tv purchased with extended warranty

Address:

Mumbai City, Maharashtra, 400053

I purchased a lg tv with kohinoor televideo, andheri and want to avail warranty service. Voucher no. Sls4035592.. Dt. 12/06/2017. We have paid for extended warranty of 2 years at the time of purchase. Kohinoor never gave me amc kit and i came to know about the kit 2 days back when i called up customer support. Now neither kohinoor nor lg is giving warranty service. Kohinoor says money was paid by customer but policy was not taken by them. What is this? Customer is getting cheated. Please help me to get warranty service.
