Worst service ever

This is the second third time I’m writing about the same issue and it’s still not resolved. I had a debit issue previously, however, I received a call from someone advising that the error was on Vodacom and that the matter is now finalised as there will not be any further debits. However when I checked my credit record on Clear Score, I noticed that Vodacom is now listed as an account which I have missed payments on for December 2022. This has subsequently led to my score dropping significantly and being negatively affected. I would like to request that you please rectify this with the relevant institutions to rectify and reverse the negative impact on my credit history. I would therefore like for Vodacom to erase this mistake so that the Vodacom missed premiums that was never my failure to begin with, does not reflect on my credit record. I just called this morning and spoke to an agent by the name of Shane in the legal department who just hung up my call without assisting me. I told him that Vodacom still appears on my Experian Credit record as a missed premium for December 2022. It is not supposed to appear because I never missed a premium. The contract was cancelled in October 2022 and you guys were not supposed to debit after that.
