Bad service by ******** Wesbank Consultant

I made arrangements with Wesbank and kept to my deal. Only because I made the payment arrangements earlier I'm told I am in breach of agreement because I paid without calling. Then I get this message requesting me to pay the same amount I paid earlier on. When I called in the phone got answered by Mark. He is very rude and was the one to speak and didn't care to listen. I don't The line then got cut and he never even bothered to call back. What ever happened to telephone etiquette and treating clients fairly. I called with my own airtime wanting clearity and this is the treatment I get!!
