sir-gilmour i can't see your response?

Hi, i recently applied for a mortgage with C&G, having never had problems applying for mortgages before. The mortgage was agreed in priciple, although they needed to write to employer to confirm commission earnings after around 3-4 weeks of too and fro. Inbetween the times of applying and them writing to my employer, i was offered a new job and current employer asked me to leave straight away, and hence detailed "No Longer Employed" on the reference form from C&G. They then took that as fraud and and think i was lying about employment details, and placed a CIFAS Cat 4 against me for fraud and forgery (the forgery i dont understand as they wrote directly to employer). I have written a letter to C&G saying i've never had bad credit, never been declined a mortgage and have committed fraud, however i need to re-mortgage the house and am looking at getting car finance around June time this year. Am i stuffed, or will current lender let us move or re-mortgage if we have to (considering we have over 2 years history with Halifax with no payment problems)?! Really need to release some equity from house after doing it up, and am worried that C&G wont do anything, although i have been told that it should only last around a year if nothing else is highlighted? Help appreciated.
