All comments taken on board thanks. Just to update, we got a reminder yesterday saying payment overdue and would be cancelled if not paid by 22nd Jan. I phoned ABTA to get their take on it. They said despite my complaint and note that I am not paying until situation resolved they are within their rights to cancel the holiday as per the terms and conditions of the contract despite the bad practice and possible breach of ABTA guidelines.

So i phoned and paid it! The girl on the phone said she could send me copies of all of the receipts but not a statement as such. It is so frustrating, if they'd have done that when I asked in the first place I probably woudl have never bothered complaining and getting into such a muddle over it all! I still would like a response to the letter though, just to see what they say.
