Persistence! I went through a phase of emailing and calling Amanda Walsh but did feel a bit bad as she has technically left the company. I emailed roomsnet everyday and was just lucky I think. It took me 4 Weeks though to get the refund and they have said to me there is still a back log of refunds they have to process.
I cannot believe that they are still doing this though. I think someone called Michael is now in charge so try emailing
help@roomsnet.com and ask for him explaining what you had been told and what's happened. They seem to respond it just takes them a long time to sort things out.
I'd book somewhere else before you go so you don't get shafted when you're out there as paying at reception is so much more expensive than booking online, just use an ABTA or ATOL protected site. Travel Republic are brilliant and helped us when we got stranded in Salou.
Good Luck!
