VODACOM - THE WORST

Worst service provide ever. Had 3 contracts with them. Contract ended on 15/01/2021. Called them on 15/12/2020 to cancel ALL contracts. Final payment to them to be made end of Jan 2021. Turns out they only cancelled 2 out of the 3. Phoned them again on 12/02 when I received a new invoice for a contract that was supposed to be CANCELLED. Was promised that is being "escalated" and that my account will not be debited. Debit order is cancelled on my side. NOW I keep getting phoned and accused that my account is in arrears, but according to me this contract is supposed to be cancelled. Phoned again on 15, 16 and 19 March, everytime it is a different excuse, and a different agent. Requested the voice recordings of all my calls regarding this cancellation on 15/03, but still waiting. Call centre agents have no manners, and does not actually listen. just keeps on saying, "I understand your frustration, and it is being escalated". Asked to speak to a manager, but they were all in a "meeting". Still waiting for the agent and manager to phone me back.
