Failure to allocate data

I have a modem contract with Telkom and never missed a debit however I did not receive my monthly data allocation for November. I loccked a call with them and they acknowledged the problem and undertook to investigate. Their turnaround time on the matter was 72 hours however its been 2 weeks now without any luck nor anybody giving a feedback. When I call them, I am told that they will send an email to the relevant dept. dealing with the matter. I am so disgusted at their competency an dealing with the matter.
