Dear bank,
I humble request you to kindly take necessary action against your credit card recovery agent Name priyanka, calling no.[protected], because she called to my old mother and others members for credit card bill payment.last month I told to recovery team I unable to make payment total outstanding due to heavy financial load on me.I told him to settlement my card with minimum amount, but they denied, so what can I do.I am helpless, and if your team again called and harassment my family then I lodge complaint against him/her in police station.
With regards!
