I WILL OPEN A POLICE CASE AGAINST MTN FOR THEFT!!!

My SIM only contract was cancelled on 26 March 2021. I am still been charged for this despite dozens of phone calls and e-mails between MTN and Mondo and my HelloPeter post on 29 April, to which MTN has not even bothered to reply. So my next communication with MTN will be to give them a police case number, for theft. ATROCIOUS,NON EXITENT SERVICE!!!
