Today i got a call for my credit card due payment where in i clearly inform that i have already paid my debt last night & please check the same, the executive was extremely rude & talk like giving threatening to me. Even i acknowledge that i'm recording this call still he was very rude. Poorest customer service also i will complain the same in board as well.
