Axis Bank — signature of pan card not matching with the one you have already got

Hyderabad, Andhra Pradesh

Respected sir
My name is shyam reddy. I had taken home loan from axis bank hyderabad 3 years ago. Now iam selling that house the purchaser has also taken home loan from axis bank as we suggested him. Loan has been sanctioned for the purchaser some 25 days ago. Purchaser has taken cancelled check and id proof from us. Purchaser has told us that by removing the loan amount he would give us remaining amount. Today that is 31 july 2017 we got a call from the bank stating that the signature in pan card is not matching with which they have in this way they are troubling us. The main thing is we gave the same pan card with same signature on the day we took the loan. Without seeing anything did the bank sanction us the loan?
