Muthoot — Fake information on discount

Muthoot is giving offers for NPA account. If customer close their account they give flat discount of 10% on interest part. So I tried to clear one loan account by transferring the amount as told by Muthoot staff. After receiving the payment Muthoot employee is saying that sorry you will not be able to get discount of 10%.

This is totally unethical and we need a solution for this.
