Cell not changing their debit orders.

This is a follow-up on my previous review of Cell C. On 4 July 2024 I comp**** with a Cell C request for a cancellation letter and a copy of my ID to cancel and convert my cell number to pre-paid after making the same request by email on 1 June 2024. Eventually Cell C converted my cell number to pre-paid and I transferred my number to Vodacom. Now, for the last two months Cell C is still debiting my bank account for both number my cell numbers and I am obliged to pay my bank R25.00 per reversal. For my second cell number I am transferring R151.08 by EFT to the Bank account of Cell C.
