Telkom billing ******** people

Please help me understand why I'm still being charged for R202 for a contract I canceled in February on *** number?? I have 5 ref's ***5,***3, ***2,***9,***9 and LOTS of emails, calls and even went to their branch to resolve the matter, even blocked them from accessing my account but they changed a debit order reference so they could access my account AGAIN!😭😭 why **** people?? What exactly am I paying for🤷🏻♀️🤷🏻♀️😡😡

I don't even get invoices from them anymore,they just go to my account and take my money and never bother resolving the reference numbers they gave me, instead they keep giving new reference numbers but none of those come through to say issue has been resolved and call closed, it's new reference numbers ALL THE TIME!
