I completed the loan amount in the stipulated time and after asked the bank manager to give me the loan clearence certificate then they told me that they will send the certificate by post I will get it aftet 15 days.But now after six month I have not yet get the certificate.A few days ago I called the branch again they told me to pay five hundred rupees again for the certificate.why I have to pay now.?
