BAD SERVICE SO DISSAPOINTED

I am with Absa more than 30 years , I have a credit card for many years with them, I pay them every month , this month I paid R130.00 short, I was phoned by one of the controllers telling me I missed a payment , and this will go on to my credit record. I checked my record and could not believe my eyes , they listed me as no payment received after I went and paid R200 extra on my card. Absa is this the type of service you rendered to a 30 year client . What a disgrace I never missed a payment once on my card, you dont care about your clients , what a attitude. Worst service ever, but I don,t think you will even respond.
