I cancelled my Vodacom Insurance on my modem and cell phone on 23 September 2021 with immediate effect as I had decided to go with another insurance provider. The agent on the phone informed me that I would get an SMS in the next 48hours. I did get the SMS but when the I got my invoice this month I saw the insurance was still on my invoice. I called Vodacom insurance and told them to please sort this out and I demanded a refund for the September Debit order as there is no need for me insure 1 device on 2 insurance.

Please may this be sorted out and may I please have a refund or be credited for this. I have a ref number ***.

No one has contacted me since I logged a call on 14 October 2021.

Thanks
