incorrect dis-connecting

Mobilesplus disconnected my phone number incorrectly, saying that I had an outstanding balance, which however my bank account was deducted on the 30th of October. I then call and send through proof of payment and yet I now I am the one that has to wait 2-3 working days in order for my phone to be re-connected. MOBILESPLUS' mistake yet I am the one that has to suffer and be without my phone which I rely on for working purposes!!! absolutely shocking service when they are in the wrong and no sense of urgency for their customers. I work in the retail industry and I do not find this sort of service acceptable at ALL
