Discovery Vitality communication

On 29/11/2019 I sent email to Discovery Vitality requesting cancellation of my Vitality membership with effect from 01/01/2020. Receipt of my email acknowledged 29/11/2019. Unauthorized monthly Discovery Vitality deductions continued from my bank account up to June 2021. The first refund was effected on 30 June 2021 for an amount of R 2130.00. This was for premiums of R 355.00 for 6 months. The second refund was effected on 17 August 2021 for an amount of R 4080.00. This was for premiums of R 340.00 for 12 months. A interest refund of R 100.57 was approved and paid out on 31 August 2021. My dispute with Discovery Vitality is with the interest payment of R 100.57 as this does not cover the financial loss to me over the period that above unauthorized deductions were made from my account. The refund should reflect market related interest for the period from 01/01/2020 up to the refund payments received into my account and up to the date of the belated interest payment. Numerous email requests request to Discovery Vitality to provide me with Discovery's calculation of interest ,arriving at a interest payment of only R 100.57 were met with a reply acknowledging receipt with a reference number and thereafter ZERO further action from them ! This is my final request for a market related interest payment for the unauthorized withdrawals from my account. Kindly respond by email to : ***. Des Smith Membership number: ***
