Do not get a contract with vodacom, you won't get out

After paying R8826 on the 16th of July 2024 to cancel my contract and being assured that it's done. Vodacom has debited my account again on the 1st of August. I phoned vodacom and eventually was told by the consultant that it's sorted and I owe vodacom nothing. Now I'm not even in the country anymore and I get sms's that my payment plan with vodacom has been captured. And now this morning a sms to remind me that I owe vodacom R1465.03. I called your call centre using roaming and 2 times the phone gets put down as apparently they can't understand there will be a delay in answering due to me being in another country.. I need this sorted
