Absa has my account on hold for no reason!

Hi Absa. I need assistance with my business account. My business account agent told me I needed to travel back to SA to reset my PIN for my online banking. I did just that, all the way from UAE. Only to be told that my account is actually on hold due to there being ********** activities reported on the account. Now this account has been on hold since Covid 19 hit and I haven't been able to travel back home since. There has been no communication with regards to my account being on hold, no court orders. The person who reported the account is now AWOL and I understand the consultant at the bank could not give me their details but I need my account unblocked. With no actual reason as to why the account is on hold, how can I go about getting use of my account bank also note despite the account being on hold and me not being able to do any transactions on the account I am still being charged my monthly fees. Just help please? I am not in South Africa now. I can only be contact via email or UAE mobile please ad 00971 to the mobile number added.
