Poor customer service

Fnb is in the business of draining customer accounts, after a missed 1 payment for my bond due to my partner passing away and having to revise my finances, I then made an arrangement,off which fnb never debits for the arrangement but prefers to harras me, fine I make manual payments because fnb can't do debits, as if that is not enough now fnb is debiting me for a connect account which I did not sign up for can I please have my money back
