Vodacom Den of ******* (Unable to Honor Contract)

Vodacom Den of ******* do not accept any contract with Vodacom. Vodacom Consultant contacted me in June 2023 offering an upgrade for my contract with promise that Vodacom is offering me for less. But in July Vodacom debited my account 50% more than what is actually agreed upon the upgrade. It now three month calling sending e-mails and still no help what so ever - but the minutes i start reversing their debit cannot stop irritating me with their calls. Talking of den of ***** is Vodacom second name
