Credit never passed.

For almost two years I was debited for CLIP, when it was supposed to be an all-inclusive package (I have 2 phones, same contract, signed on the same day with the same person, where one is charged correctly and the other not). I have raised this with Telkom several times. Eventually, it was solved, according to the SMS I received relating to my case number. However, since 4 September (when according to Telkom when it was resolved "Good day, a credit of R119.21 have been passed for CLI...") the credit was never passed on my bill. Where is my credit?
