Fast Deals Today — Wrong product selling

I have ordered Sony company Earpod which have offer buy one get one free. When I got this order today it had i7S TWS company Earpod. They deliver only piece of Earpod where it has 2 piece of Earpod. Instead of delivering Sont Earpod they have delivered i7S. That also one piece. i7S Earpod market price in Rs. 317 where they have charged me Rs. 1100 for the product Sony not for I7S.

When I tried to call the marchent his/her mobile number [protected] is now switched off. There is no proper address or contact number where we can raise the complaint for this.

Thanks,
Anand
