BEING BILLED AFTER SETTLEMENT

So I bought a new vehicle and my old vehicle was settled by the dealer I phoned in advance as the dealer took to long to pay the settlement and I tried to make an arrangement for the d/o not to be taken as the settlement was in progress. These guys just threw there hands up in the air unable to assist me causing for two of my d/o to bounce and now I have defaults on my name as well as for arrears payments as this bank is so UN-helpful. I want my money back so that I can pay my other d/o as well as a letter of apology and need a letter to be provided for the defaults to be removed as this is a inconvenience and makes me look bad. then the above mentioned so called team leaders attitude is abrupt and bad. This person tries to make me look like a fool, I'm not UN-educated so no fooling me or making me look like a total ****. No public relation. Next step is the Ombudsman for all parties involved causing this havoc.
