Vodacom

My services at Vodacom have been suspended due to late payment. I have made a payment to them on 10 October and sent proof of payment on 12 October after my payment still did not reflect on their system. I have called them 7 times on 13 October. On the 3rd attempt I got through to a consultant. I just started talking when the line went dead on their side. I phoned again and each time the computer voice said they see I've been trying to contact them several times, they will call me back. They do not call me back and I cannot get through to them now, because I keep on getting the same message.
