I have booked a week in Gran Canaria for Dh's 40th birthday next May and paid £120 deposit at the time, a few weeks ago.
Today I received an e-mail asking for £400 within 14 days. They imply that I took advantage of a low deposit at the time, knowing I would then have to pay this £400 shortly after, yet I don't remember that at all.
I don't have a spare £400 floating around at the moment, I was planning on saving £100 a month between now and March, when the balance was due . Looks like I'm going to lose the £120 deposit then.
