Vodacom Insurnace

I am very disappointed with Vodacom Insurance, last year August I upgraded my phone contract with Vodacom in Clear Water. All was well and the service was great, come April I notice that I am being over charged for some reason. When i check my statement I realize that this was done for the month of March as well. I contact the Vodacom call center and they tell me that they cannot assist I need to contact Vodacom Insurance. I am then advised that when I did the phone upgrade I also took out insurance, I ask the agent to send me the contract because I don't recall doing so. I view the contract and I advise that the signature on the contract (which is literally my initials and surname) does not belong to me and I would like a refund, apparently a consultant sent this through from Vodacom Clear Water. I have called numerous times being sent from pillar to post at some point being told their accountant is not available and this will be sorted after COVID. I called again today and was advised the person that can assist me is still out can I call back later. This is very frustrating and annoying when these amounts are being debited from our accounts there is no COVID issue but now paying me back what is rightfully mine is a problem. Vodacom please resolve this ASAP.
