Club Factory — my money was sent to someone else

Address:

395007

Dear sir/madam,
I ordered a product from club factory (Cf). I paid through my card.
They sent a wrong product. I returned it and claimed refund.
They refunded the amount in my cf account.
It was withdrawn into someone else's paytm phone number, which is : [protected]
Now, cf is telling me they cant do anything. Firstly, i did not pay via paytm. I paid via my card.
2nd, this is not even my number
Someone else's number is registered in my account and now cf is not helping.
They only reach through chat on their app... They dont respond on that chat and close the window on their own.
Their number [protected] is not picked up before 15 minutes everytime i call. When they pick up, they disconnect without listening to my problem.
They have been providing me refernce ids without any resolution.
Here are the refernce ids:
Reference id: 776086
Ticket number #795095
No resolution. Please help!
