Failure to provide customer support or feedback

I am beyond frustrated with FNB and fed up. I have sent through all my documents confirming that I have been retrenched and can no longer pay my loan. I have tried numerous times to call in and follow up on my credit protection plan to cover the loss of income and can never get through to anyone. This morning I have been transfered 6 times and no one can help me. This morning I received and sms to say I must make sure there is enough funds in my account for my debit orders to go off. I have been retrenched, I have no money. Can someone please resolve this as soon as possible, this is extremely frustrating
