I can get you a brand new, up to date 50" Samsung TV by tomorrow for £699 and I'll set it up'.  We foolishly agreed to that,

Assuming you agreed there and then rather than after he had left this sounds like off-premises to me, right of cancellation would apply, presumably no terms given, if so 1 year and 14 days to cancel for a full refund OP.

From what you've said the issue might be enforcing that.

Isn't this ^^^ the only issue? 

As the "engineer" seems to have provided no paperwork - and quite possibly doesn't even know what an off-premises contract or a cancellation period are - any discussion of "scams" or what mis-selling means seems unnecessary
