DEBIT ORDERS

I have an instruction in place to not allow certain debits to not be deducted from my account. tHE DEBITS WENT OFF. As these amounts are over R250 I cannot do this via the app or internet bank nor the cellphone banking option. Returning debt order have been disabled as an option when calling the call centre and FNB staff no longer have access to return debit debit order which are in dispute by the fnb customer. I am unable to pay my rent as my landlord still wants his rental and I am unable to purchase medication for my 4 chronic asthmatic children and I am unable to purchase food as I do not know how to move forward if I cant return these debits. Despite the fact that there is funds in my account I cannot spend anything as the funds have been budgeted for. My kids medication alone is over R3k my rent is R7k School Fees R3.6k , water and electricity and Food ?????? . I have already spent R210.00 in airtime holding onto the call centre trying to get hold of a consultant and when i eventually do i get told they will trsf me to the correct persons to return the debits only to hold on until my airtime runs out. I want the amounts of R1026.00 and R1200.00 returned immediately
