I had an outstanding debt that I had fully paid on Sept 21, 2016. On Oct 3, 2016, Citibank's collection department promised to send the certificate of full payment within 20 banking days (soft copy) through email, and 30 banking days for the hard copy to be sent through mail. I've been calling Citibank's collection department for 3 weeks now to check if they have already sent the certificate, but they are just giving me different names and phone numbers, (all 7 numbers are being redirected to a voicemail until now) to call to ask for the certificate. They were telling me that my citibank account was already being handled by a third party collections agency (GCCS & Associates). Now, no one from Citibank is willing to assist me. Please help.
