Reliance Digital — reliance digital worker used his credit card as ecs in my account

Address:

Mysore, Karnataka, 570004

I purchased a mobile for my friend on May-10-2018, a person who works for reliance digital (Govind) have given one more mobile to my friend as he is a good friend of Govind. After that Govind came to my office and took the signature of mine to the documents saying his job will go if i wont sign and he will take the responsibilities of the payment. Now when i see the bill in my mail i saw that Govind have swiped his credit card for deposit of that mobile and have made ecs too. My friend and Govind have mingled in this and now they are troubling me for the payment. I request you to do needful thing. The bill has been attached.
