FNB THICK AS *******

I'm applying for a working visa to Australia which requires applying for subscription to Australian medical aid. My visa application has not yet been approved, i was supposed to start working on 1 Feb 2022. I requested that the medical aid subscription be deferred. Realizing that this would not happen because i did not get any response from the medical aid company, i transferred all funds from my FNB cheque account to avoid payment. I don't have an overdraft facility. Lo and behold FNB authorized payment from an empty account. ****** by the Australian medical aid company, ****** by FNB!
