Muthoot — fake loan payment by the muthoot group

Recieved two loan payment posts from the muthoot group, which was never applied for. Never taken any loan from the muthoot group.
When called the branch office (R k puram) the customer service was so bad plus they had no information like no id, no correct phone number just the name and address.
How can you issue a loan when you have no valid id.
Is this a scam or what?
