Cell c breaches contract and managers dont follow up.

I had a 2 year contract which was taken up on the 12th of Feb 2019. I was paying R305 monthly. I was dead set on finishing up the contract and cancelling once payments were finalised end of Feb 2021 however an agent called me on the 8th December 2020. He offered me 5gigs of data on the sim that i had for R75 per month and advised me that the december payment will be R305 as normal but from January 2021 i will only be paying R75. I thought that was a good deal as i hardly use the sim and router and well R75 for 5gigs, well worth it. I accepted.

On 26th Jan 2021, here come cell c debit, in excess of R500, R521 or somewhere around there, i call customer service, told them about the call on the 8th of december, apparently the agent didnt capture someting correctly and they wanted to amend everything. I was and am still furious because that was not what we agreed upon. I requested to speak to a manager and wanted a copy of the call made on the 8th of December. It was definitely a breach of contract from cell c side. However as advised, i was willing to pay off my initial contract, the R305 until it was paid up. So basically Jan and Feb, then contract done.

A month later Cell c agents call me to tell me i owe them an amount in excess of R900, and for what, coz im not paying my contract, i advised the agent to view notes on the system and requested that their manager contact me and send me the recording for the 8th of december, once again i advised im not paying gor something that i didnt agree to, however i will pay up my initial contract...

Almost 2 months has passed since that call, i still havent heard from any of the cell c managers or even received a copy of that call made to me on the 8th of december 2020. Cell c, what the hell is going on? If this affects my credit history, im going to take the matter up legally against you because this level of service is pathetic...
