Gary,(posted 8500 days ago)I think you should be clear that you are asking to see the mortgage deed (& conditions) and not the title deed. (But of course they know this. They are obfuscating.)
I know of others who have had the 'are you saying you never had a mortgage?' response. This is a disingenuous response, but of course it's an interesting one because of its lack of focus on the real issues raised by you. Take Lee's advice, is my advice. And good luck & all best.
