Poor service - No Feedback

On 28/04/2022, my account was debited by Vodacom with an unusual high amount. I immediately contacted Vodacom the same day to query this amount (10x my normal installment). according to the agent, data purchases was made, of which I advised them that I did not make those purchases as this sim card has never been in use. A case was logged for this matter to be investigated. I made weekly calls to Vodacom to follow up on this matter, since Vodacom never gets back to me. The matter was referred to the ***** department, after which they requested for my ID and Affidavit. I have have sent these documents to 5 different email addresses and even after following up weekly on this matter, to this day, no feedback has been received. My credit record is being affected by this, while I've been waiting for 3 months to get this matter resolved. The reference number is: ***. I urgently need this matter to be resolved.
