Holiday company adding £954 at checkout

[cantfindamoniker]

Trying to book a holiday and each time I press 'book' on either Tui or First Choice, both add hundreds extra at checkout with the pop up 'this holiday has increased by £954 while you have been on the site'. I've tried 4 different devices, using data rather than wifi, still the same. Tried different dates/holidays and as I book the pop ups have been £752, £864 and now £952. So frustrating. We have given up. Anyone else managed to avoid this? I've been trying a period of over 3 weeks with the same result. I can't believe every flight changes every time I attempt to book, surely?? Feel like Tui and FC are taking us as chumps! Grrrrr

I honestly think there is a problem with the website, it’s not normal for so much to be added on upon checkout

I know someone else who had this problem with Tui. Ended up in a Twitter discussion with them. They resolved it eventually, so contact them directly and say they are being misleading.

Thanks all. I'll phone them tomorrow/next week. I hope it is the website...
