Cell C account and customer service department is a sham!!

In February this year I found out that I owed Cell C money, which was news to me. I did some investigation (A lot of time, energy and money spent) to find out what was happening. Eventually in March, I find out that the service agent that I used to get my cell c fibre account never loaded my first three months free and this was the money that Cell C claimed I owed them. I then spoke to a seemingly helpful lady at the fibre call centre who helped me (or so I thought) to sort out the credit. On 25 April I received an email to say that the credit has been approved and will be deducted from my account in 7-14 working days. Today is 13 June 2018 and this credit has not been passed. Cell C keeps deducting money from my account for the amount that they think I owe them. It seems as though the service and accounts departments do no communicate to each other and neither does the call centre communication with customers regarding open complaints. I have now reached a level of frustration that has caused this message to be loaded. I think I have given Cell C enough of a chance (given the 4 months I have been contacting them) to sort this out. I will be contacting the Consumer Goods and Services Ombudsman as well as the National Consumer Commission to assist with resolving this issue as Cell C has not come to the party.
