Consumer Redressal

I hold an Indusind Credit Card. Now the amount is due for payment however there is some problem I am not able to make the payment. I have severally requested them that I will make the payment on 29.04.2014 but they are not listening. Every 5 minutes they are calling and asking for the payment. I went to the IndusInd Bank and requested them to extend just 3 days for the payment and they agreed. However just few minutes later again I have received the call from the recovery agent of Indusind Bank and claiming amount and abusing and torturing me for not paying the same. My request was to grant me for 3 days extension time period for the payment however they are giving me pressure and abusing and torturing me over phone.
