FNB will not downgrade your account

Requested a downgrade of my Cheque account on 15 December 2025. Was told ot would take 5-7 workong days. Followed up 26 December, 6 January, 19 January, 21 January and 22 January. 26 January when I followed up after being billed in full for a account type I do no longer want I was told the downgrade was processed. No communication from FNB. Not acceptable service
