We have just had the something simular happen to us.
We booked online in March for a package holiday in June and they rang us yesterday to ask if we would take evening flights instead of morning flights. We said no as they really dont suit us so they siad we dont have a choice we have to change.
So after numerous phone calls we were offered either cancel with full refund, not an option we want a holiday or so called alternative holidays which were not even in the same country never mind the same resort, some were up to 11% more expensive, not the same facilities basically whatever was left over at this stage.
The new flight times really dont suit us and as one of us will be arriving back in Dublin late have to travel for a further 2 hours and is working the next morning. Of course they told me it is the terms and conditions that they can do this but no matter how much we begged and pleaded no joy. In fact we were made feel we were being unreasonable.
They sent us through letters to be signed that they wanted returned today. Assuming (uncorrectly I have access to a fax machine) or signed and returned by email. I asked them how did they imagine I could sign it and return by email. (Yes, I have heard of scanners but that is not the point). Or by post only if they have it by Monday, I'm good but even I cant influence An Post.
Never, ever again will I book with this company, yes these things can happen but we booked in good faith, paid in full and maybe if they had been honest and professional in their approach with us and admitted they had over booked the flights, and told us in the begining that we had to change there wouldnt be such bad feeling now. But were not the easiest company to deal with from the begining, we booked online to avail of the slight discount, I will be returning to my travel agent from now on, I know these things can happen but a travel agent will make some effort to take your needs into consideration (in my opinion.)
