Poor customer service from Joyce

I am not happy about Joyce customer service.I received an email that I only paid for February and I also sent her proof of payments with my reference number for Jan/Feb she did not get back to me and tell me this has been fixed or what.I can not owe R2,5 and end up paying R3000 l.I will personally take this to ombudsman because I do have proof of payment for 2 months yet your statement only shows February mxm.poor sevice Joyce
