Prepaid airtime won't go through

I have been fighting with Cell C for 3 months now because I can't load prepaid airtime via internet banking.<br> I have been told that the problem lies with Absa. I can't find a number on Absa's website for internet banking queries. I also can't phone the bank because Cell C charges exorbitant amounts to phone TOLL FREE NUMBERS.<br> <br> Absa please phone me back and help me. I have lost a lot of money on airtime that hasn't gone through and Cell C keep on telling me that the problem lies with the bank.
