Insurance dispute

I am experiencing a serious challenge with Telkoms Insurance_Finrite

I'd like request that I be refunded for the amount of R 151.00 reason being,

On the 13th December 2018 at 11:42 I contacted the Telkom Insurance (Finrite) call centre to cancelled my cellphone insurance , the call center agent that assisted me was Priscilla she informed me that there was a 30 day notice and that my account would still be debited at the end of December 2018 which is understandable. However at the end of January 2019 my account was debited for the sum of R 151.00. In this regard I contacted Finrite again to report the matter and to request a refund. The call center consultant I spoke to advised me to draft an email and send it to Finrite which I did on the 10th February 2019, no response from Finrite to date. At the End of February 2019 my account was debited again for the amount of R151.00 and I contacted Finrite again to report the matter and the call agent who assisted me this time around informed me that on the system it reflects that the matter has been escalated but she could not indicate when we can expect feedback, nonetheless my account has been debited again end of March 2019 for the same amount and am completely fed up with this inconvenience, I tried calling the call center today 02/04/2019 several times on the following number ***and the number does not go through at all. Please assist with this matter.

To date Finrite owes me a sum of R453.00

I am unable to reverse the debit order as it is linked to another contract I have with Telkom.

Looking forward to your response.

Kind regards, Nomthetho
