Bad review

This is unacceptable. I have made a payment on the 28th of December. My line were disconnected due to non payment after i have done a eft. I have spoken to 5 people now and sent the proof of payment to 3 different people still nothing. I have even sent the proof of payment to the cell c proof of payment email. Still nothing. I spoke to my bank according to them the payment shows successful on their side. I want this sorted out asap. I am really on the verge of changing to another network. This is bull ****.
