Webafrica and Vumatel take payments but zero customer service

I keep having this problem with Webafrica and Vumatel. My payment did not go through because my limit was not adjusted....due to ***** I keep a limit on my bank account. I used the link webafrica sent and payment was successful. My service is disconnected since this morning. I tried messaging them on Facebook and sent them 2 proofs but they are just ignoring me. Am I supposed to sit and wait for them to decide to reconnect my fibre... I cannot work without fibre. Why send me a link to pay and then tell me you cannot locate my payment? Even after I sent you 2 forms of proof?! Very *********** staff.. Pathetic customer service.
