Locked out of Capitec Business Account

I am now sick and tired of Capitec Business banking. Since the first day I have endless problems with my account and now I am locked out of my account for no reason. They have updated the App send an OTP and the App gave an unknown error and when I tried using Mercantile App it said that my account has been locked. I have contacted the call center by the number they give on the App and the call center agents are not very help full of getting the account unlocked. I think if the account get eventually unlocked to close it permanently.
