PATHETIC CUSTOMER SERVICE TO A PAYING CLIENT.

I received a call in May around the 26th regarding a payment arrangement for my tv licence an agreement of R100 will be paid until the full amount is settled being R318. To date I have stuck to my end of the agreement I even received an sms stating in May 28th after I paid my first R100 that R218 is the balance outstanding. I paid up my last R118 this month only to get a response from PAM stating there was no proof of payment that I had to pay R242. The same person I have told that I dont get her attachment on my emails and I sent proof of payment so HOW IS IT THAT IM STILL OWING???? I called in and GUESS WHAT?! I OWE R124 which could be because I paid on the 28th and not the 27th!!! I emailed PAM and received a GENERIC RESPONSE TO PAY R242 with no proof of why two different mounts or where it states that payment must be on the 27th??? seeing as though my money reflected in the evening I was suppose to drop what I was doing and make payment????? There is no agreement on this and as per my sms I was owing R318 which has been PAID. I want this issue sorted out immediately as I find this very fraudulent and breach of agreement. That your staff chooses to IGNORE.
