Billed twice

I really can't take FNB any more.1 I get paid on the 25th not the 24th if the 25 is on a Saturday I get paid on a Saturday,before I even get paid I get sms that I missed my bond as I promised to pay on the 24,who did I promise to pay on the 24th?2 um under debt review because I have a lot of debt right,so um not anymore but um still not affording life u know but why are debiting me twice I meant hey took all my pay.um changing the banks this is too much at least um paying now,the other I was on behind on my bond,but now I finish pay the arrears but guess what FNB my bank is debiting more without my agreement.um done paying the arrears so now,um I suppose to survive this month if my bank does this to me
