payment still not allocated.

I asked to cancel the debit order, as I prefer to pay my own account, nothing has been done, debit order is running when ever cell c wants to, not even on the date we agreed on. I made a payment end of september, which no one can find. I phone how many times, I have faxed proof of payment and emailed it. again I had to phone, received a ref number and promised to get feedback within 2 day, I'm still waiting. Again my line is blocked, with no answer and still no payment allocated. I have cancelled two of my lines with cell c and will love to do the same with the third and final contract, if the line is not activated and the payment is not traced before close of business.
