Cancel a contract with Vodacom - Nightmare

I want to cancel my cell phone contract with Vodacom. Went into the store one day, find out cancellations can only be done over the phone. Contacted Vodacom, spoke to a consultant who advise me that the request was logged and I would receive a confirmation email/sms within 24-48hours. That was 17 June 2022 at 12:00. Still have not received an email or sms...... Then end of June no debit order went off, I thought well the contract has been cancelled, nor worries. Well, July comes, guess what, another debit order goes off for my Vodacom contract that should be cancelled. I sent the debit order back to the bank for reversal, now my credit score is in the red due to not paying this outstanding Vodacom bill. Phoned Vodacom 5 times between June 2022 - August 2022 to cancel the contract, each time to hear that the request has been logged and I will receive a confirmation email/sms within 24-45hours. ABSOLUTELY SHOCKING SERVICE!!!
