Harassment, Terrible Service and Administration

Terrible Service and Administration!!!! My vehicle was settled on 11 November and the proof of payment was sent ON NUMEROUS TIMES but Wesbank STILL keeps on calling and sms'ing me that there is an arrears amount. I have requested my NATIS documents to be sent but no one seems to know what they are doing. I'm literally being harassed for money I don't owe! I'm getting two two four calls a day and each consultant (every time a different one) has no idea what is going on. Seems like they don't have a system where they can make notes, and are the calls even really recorded? My account was referred to Innocentia from Colserve whom I sent the proof of payment to as well and I haven't heard from her!? What is up with these people? I never thought WesBank could be so poor at administration and service. And the consultants are so ******** and arrogant.
