Moto TPSL — credit card reward points

Your customer care has called me up regarding updation of credit card reward points (13.03.2018, inv. No. [protected], ref. No. 74678448073000002869989). I have never used my credit card. I was told that i will not have to pay any money regarding the same only reward points will be credited in my account. I clearly told that i have been provided a credit card, which i am not using and will be surrendering the same. But still they put the reward points in my account. Now when credit card statement has been received, i came to know that i have to pay rs.8377.

I have never used any credit card in my life then why should i pay the money.
Please cancel all the charges /reward points.
