Products changed without clients knowledge with major consequences for client!!!

I banked with ABSA for 22 years. I opened a Notice Deposit account with them about 5 + years ago, I then moved banks for a year and went back to ABSA, hoping they were beter. I never closed my Notice Deposit account, it was still active when I had the profile opened again and started depositing money into this product. However I noticed that the money being put in did not show as available on the platform. I went to the branch and queried this only to find out that this account is now a 32 Day Notice account.

I asked the lady how did it change to a 32 Day Notice account as I have used this account for the past 5 years no problem but now I need to give notice etc.

I want to under how did this notice deposit account change to a 32 Day Notice and when was this changed.

And, how am I now going to get my money without giving notice as I did not request a 32 Day Notice account.
