Theft and no communication at all.

I logged a previous hello peter complaint on the 23rd of October 2020. No one has contacted me till today. I logged a complaint with the ombudsman ( CAS-128051-M2J4Y0) As I called MTN customer a numerous number of times and no one could assist me regarding an exorbitant amount of money R5121.20 and I signed up for 462.20. I called retentions after not getting any feedback from MTN to cancel my contract and Lereko Mabeta assured me this was an error and will be fixed. after been debited double my normal amount I sent him an email and since then he has not yet contacted me. I cancelled my contract and MTN still debited me R5121.20. MTN wanst to now list me on the with the credit bureau.
