I have a holiday to Tenerife booked for November with TUI. I've decided to cancel and lose deposit we have paid (£100) so I don't have to pay £300 next month and balance of around £2000 in September. I thought I'd lose the £100 but trying to cancel online it looks like they say it's the 'full' deposit of £400. I hold my hands up entirely and didn't read the small print but is this correct? Don't rate my chances of actually talking to someone!
