Disappointed in FNB | Downgrading accounts

Why is it so difficult to downgrade from Premier Cheque account to Aspire? I have been banking with FNB for as long as I can remember, and I'm rather disappointed in the manner in which they been treating me as a client.

I called FNB last week and made a request for both my credit and debit accounts to be downgraded. I was assured that this would be done in two to three working days. I made a follow up yesterday (Monday, 2 August 2021) and I was advised that there hasn't been a request to downgrade my accounts. I was later told that the turnaround time is three to five working days (and not two to three working days as indicated previously). What is the correct turnaround time then?

This morning, I spoke to a consultant at FNB who indicated that a request was only made yesterday (to my disappointment).

I just need both accounts to be downgraded please.
