Telkom Mobile keeps *****ing money

Telkom Mobile has to be the company with the most inadequate accounts system ever. The first month after my upgrade they deducted almost 3x the amount I signed up for fir an ad on internet bundle I did not requested and wich should not be on. After logging the fault on the 3rd of November they said it was a mistake and it would be deducted from my next bill. I tried to no avail to get my money back. Now a month later I receive my 2nd bill still with an data bundle on which should not be on there. Is Telkom Mobile going to fix this or keep in *****ing my money????? Please don't waste your time moving to them, they just can't get their accounts right.
