Fullerton India Credit — Abusive calls from agencies being a third party reference

I am a reference of one of your customers. She has defaulted the loan and not paying eni due to which I am getting abusive and vulgar calls from your collection agency, have file hell lots of complaint and sent multiple mails but still facing same issue. I have been torture like anything and given bad words as well to me. I am fed up and have bp problems.

Would request you to arrange a call back from a responsible person to handle this case and close or else this time I am going to file a case against your company. Have already mailed this issue today on ccrc and crpc of rbi.
