Utterly disappointed FNB customer !

Please refer to my email sent on the 2/6/21 to ***ng a month to month contract with Rain I had cancelled the contract and they were then no longer authorised to debit my account. They debited my account on the 25th May and again on the 1 June. On both occasions I followed instructions given by an online banker , disputed these transactions on my banking app and then called FNB and was advised to fill out a debit card dispute form that was sent to me. After sending that form I received an automated response from FNB saying that their turn around time was 5 working days and I would receive feedback in that time. I have emailed back on three occasions requesting feedback and all three times nothing! Too date I have not heard back from FNB. I am utterly disappointed as my bank you have shown no interest in protecting me or my money! My card was rather blocked and I now have to pay for a new card and wait for it to be delivered to me! I am rather left to fight Rain back and will now be taking them to the ombudsman. Thank you for nothing FNB !
