I can sympathise with you.
I think that as you booked over the phone, you will have to keep paying over the phone. I dont think records can be shared for data protection reasons.
If you can get a direct telephone number(they all have them) get one, then hopefully, you might get throught to the same department all the time?
A few years ago I booked a Thomson holiday via my local independant travel agent, (who has now been bought by another major tour operator). The travel agents in question were only too glad to take my money when booking my holiday, but when it came to them answering any questions they were always far too busy!
So I gave up trying with them and called Thomson themselves, only to find out that as I had booked through an agent they couldn't be of any assistance.
I'm not knocking Thomson as a company, as i wouldn't travel with
ANY other tour operator. Just the service I recieved at the time, and this was not down to Thomson anyway. (I made sure i put a complaint in writing to the head office of the travel agency in question)!
I'm not a complainer, but I would reccomend a written complaint to anyone, even if it only gets you £10 of your next holiday, if you dont ask(moan), you dont get!
