Migration reversal still deducting every month

A vodacom consultant migrated me to a higher package on my 3 lines and I contacted them immediately. She confirmed to revert back to what it was. Never happened in the meantime deductions is going off my account. Spoke to 2 other call centre agents and none of them came back to me. After being more than 20 years with vodacom, I can't wait to cancel all my contracts with them. I've had it with their incompetence.
