Locked account

So I decided to open an account with discovery sometime last year October ,I spoke to a lady whom I explained to that I want this account for business purposes , trading to be specific and she asked me a couple of questions about how much per day do I roughly make and stuff like that which I explained and we got to a conclusion on which card will work best for me , fast forward to using the account , I would be logged out of my own account atleast 4 times in a week telling me that there’s *****ulent alert on my account so I need to verify a couple of payments that I made myself . To this recent day I’ve been logged out of my account for over a month now , said they were contacted my absa for a certain payment I received in my account , I ask what’s needed on my side and they told me, which I provided , affidavit and proof of funds ,everytime I call and get a male assistance am always told why am I using the account to trade but I bluntly explained from the beginning that am a trader and this account will be used for business purposes as am also registered as a trader ! Am so inconvenience by this bank cause what they sold me is not what am getting at the moment ! I got an email saying the investigation was completed but am still logged out and when I call they say my account is still under investigation! Please provide me with a clear answer so I can know how to proceed going forward!
