Hi ayles
There are some credit companies willing to work on your proposal if you ensure them regular payments. Offer them a realistic payment plan and stick to it. They will surely offer you some benefits in the course of time.
I remember being in a similar situation when I was getting past behind in my bills. I approached my creditors and offered a realistic plan. I didn't get the benefits from them at the beginning but seeing my payments regularly, they waived off most of the fees from the total payment.
MBNA is a tough company when it comes to making arrangements. But when they will receive regular payments, I am sure you will get some benefits from them too. Just stick to your plan
