Downgrade from current account type

It does not deserve a star at this moment. I have opted for a downgrade on my current account on the 31 October 2025. I was told it takes about 7 -14 days, but when i follow up i again told it takes about 30 days which i was still fine with. But up until now it still not done and there is no one to give a proper feedback as to why it can not be done. It is frustrating as new customer.
