Hi, My father is holding a account in sbi and he has taken loan. He was charged with wrong interest rates which caused huge amounts debited from his bank account. we also observed loan commission charges debited twice. we submitted letters, raised online complaints, sent emails, visited branch. all are done. but they are making false promises and not refunding our amount. this is pending from last two months and we were wrongly charged for April, may, june, july, august months. But we are not receiving any proper response.
