There problem, but they do not want to fix it

I have a limit on my account, R200, last month I went over the limit, the limit did not let me know in any way that I went over using data, no message to say the data is being depleted or that I am reaching my limit either, nothing, I was totally unaware until I got a sms saying the limit has been reached, I left it, and used wifi for the rest of the month, I do not phone any one, maybe once in 2 months, even though it should have notified my, nothing before, and then it went over more than double the limit, then only did they lock the phone usage for out going calls, data etc. <br> <br> It is now the 4th of November and the phone is still locked, and not registering on the data network, I now have 700mb available but I can not use it, as the network has not unlocked my phone. I phoned vodacom on the 2nd as about 13:23 - 13:30 on 111 took a few calls to get to a consultant which told we the problem is on there side and started on the 1st, there technicians are working on it, she would escalate it, and I requested a reference number, she said it would be sms'ed to me, I am still waiting it is now the 4th, no sms , no reference number, still no data service. Please vodacom I pay you allot!
