Had a massive issue with them a year and a bit ago. Agent booked me on the wrong flight, stuffed up my transfers and booked me the cheapest hotel package (while charging me for the most expensive, no doubt pocketing the rest).
Ended up having to go to court and everything but finally got it solved, however I still had to go through dealing with the upper management of that company, which is disgraceful to say the very least.
I'd recommend getting somebody else to do it, I know they're all franchised, but if anything goes wrong and you have to deal with Head Office... well I wouldn't wish that on anyone.
