I got through on the 12th July, the agent told me if I called back after the 15th July ( due date of my final holiday payment....), they would be able to amend my booking, she insisted it could only be done after the 15th. I've not been able to get through since to amend my booking. I don't intend paying them anything more until I can amend the booking. luckily, my card had expired so they couldn't take it automatically, I have a feeling I will be losing my deposit with this lot. Seems you need some website to access their live chat, I don't have one, all seems too difficult to get support. No response to emails. I would advise not paying them until you get a response.
