Bad service at it's s best

I'm covid - 19 positive and heavily pregnant, somehow FNB blocked my online banking and now they are telling me that to unblock it I need to go to the branch. Should I go to to the branch and spread covid because I need to access my funds? This is bad service on another level, and this was after speaking to 3 different consultants for 22 minutes, just to be told I need to go to the branch.
