Overcharged for Insurance

On the morning of the 13 September 2021, via customer care, I contacted the insurance department as I am being overcharged on insurance since a renewed my contract. Charmaine advised I would be advised as soon as a credit was passed. Still waiting! Have tried contacting the insurance department directly, holding on for over 30 minutes with no response! I emailed customer care numerous times, dealing with Brenda Nghonyama, Rendani Mainganya and Mujaahied Fredricks, who all advised they would escalate the problem via their team-leaders. Still no positive feed back. Yesterday I was emailed an email address for the insurance department. The email I sent this morning, bounced back with the message: *** could not be found or is unable to receive mail. Appalling after-sales service from Vodacom. Very quick to take clients money. After 5 weeks I am still no closer to receiving a credit, and keep getting incorrectly charged each month. And if I dare short pay my account, I will just get cut off. Vodacom has a lot to learn about customer care. Words are meaningless without positive action.
