Downgrade from Premier Cheque Account

I have not been actively using my FNB account for some time now so I decided to try and downgrade it to lessen my bank charges at I am not using the account to its highest advantage, with that in mind I have visited the branch closest to me at least twice and they always tell me the same thing: " the branch doesn't handle downgrade to easy but a request has been sent out and your downgrade should be complete in the next 48 hours latest" and still to this day I am still awaiting a downgrade. This is really frustrating.
