Telkom intimated that I am a ****

Telkom has now on two occasions now basically called me a ****. I bought some Data via credit card, the money was taken from my account but according to telkom it did not reflect, however I have the proof the money went off. I was told that I never made a purchase. I logged a query and was told 72 working hours, its been over a month and this has still not been resolved. I was then told that there is no way that I can purchase on a postpaid contract yet I have the proof and the Telkom portal offers that option, the conversation was ended abruptly. Does Telkom even know what they are doing.......
