Telkom

I just discovered that a mobile contract that had device insurance which ended in November 2018, has continued to billed on account even after i wrote to telkom in early 2019. They even refunded me, but then continued to debit the device insurance that was cancelled? My mistake was believing them when they said it was corrected, i should not have taken anymore contracts with telkom. More than 15 months later i have been paying for a non-existent device insurance. Then, when i call to notify them of their error, they tell me to call Finrite. Finrite sent a confirmation of cancellation which was sent to telkom in February 2019 which confirmation indicated that the cancellation was done in November 2018.
