Not happy!

I have a smart watch with FNB, that's been deducted as normal from my account for over a year, I've since purchased an additional watch and all has been fine up until i received a email saying;

Dear valued customer • FNB :-) Your Smart Device remains overdue. Legal collections process has commenced. A S129 notice has been issued. R289.00 is due now. FNB a div of FRB Ltd. Please do NOT reply to this message as it is sent from an unattended mailbox

My device is on a debit order, I've never missed payments and there is enough funds in my account. This is bizarre and could negatively effect my credit rating as i pride myself on paying everything on time. On my banking app statement it clearly says that its been deducted but why does it says it's overdue?????????

R289, i repay FNB almost R7500 per month in debit orders and loans why would i randomly not have the R289????

It's extremely frustrating because i can't speak to anyone given the time we're in! The app has extremely long queues.

There is from my side no option to transfer the money to the smart device account. This has completely caught me off guard as there was no prior warnings.
