Pathetic Customer Service

More than 2 months ago, I updated my payment method from credit card to cheq account but they still deduct from my credit card so a month ago I remove my credit card from my account and they still deduct from my credit. So I contact Webafrica and Marcia Samela answers me on the WhatsApp line, send the automated message that they gonna close the message and then she greets me and then promptly disconnects the chat. This all happened in a space of a minute. Then I connect again and speak to Nomthandozo K and I explain to here again. She comes back and gives me a screen shot 9g the failed transaction and tell her yes it will fail cause there is no funds in my Credit card, she goes ahead and tells me it's my responsibility to make sure there is funds. By this time I am ****ed so I start swearing. She asks me not to swear so I stop then I explain the same thing again l, this is now the third time. Then she continues with 8f I continue to swear she won't help me ..ok fine although * stopped swearing, I am thinking maybe she 8s just delayed so I say I won't swear and I explain again the same thing. She proceeds to send a screen shot of the details on the account and asks me to check my webafrica account. I tell her I have already checked and I removed my Credit card details a month ago because webafrica keeps deducting from my credit card. She is now insistent but that is the only details they have. I ask for a supervisor cause clearly it's easier for her to repeat herself like a parrot instead of solving the issue. She tells me I can only speak to a supervisor on Monday. This is the worse customer service I have dealt with ever!! Unhelpful, pathetic, they seem to lack the ability understand basic explanations. My next step is to change my service provider as soon as I am on leave
