FNB have not idea how to treat customers

I have been trying to cancel my account with FNB for months as they were so unhelpful during the Covid pandemic it was really disappointing. Each time its a different story. I have now been told I must go into the branch to cancel during this pandemic I must go into the bank. Last month I was told to do it via the app. The time before I was told I could do it online. FNB you are a joke!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
