Hi,I'm Zoey and I'll be assisting you. I'm reviewing your question now. Please be patient while I research and compose a reply for you.
Anything too good to be true is going to be a scam. Nobody is going to give you a $2,000 vacation and $600 in cash without strings attached. The $49 up front fee is just for the scammers to be able to find out if they have a live fish on their hook.
Either there will be another fee for much more money on some pretense or another and you'll end up paying for a vacation that doesn't exist, or the whole purpose of the so-called vacation is to make you buy a time share package which will cost you more than what you've saved from this "free trip."
These scams are very popular and for some reason tend to favor Australian victims. Scamwatch.gov.au warns of these scams here:
If you have a website for the travel company, I can see what I can find, but this conforms perfectly to the scam pattern, and I'm confident that you should avoid it.
Just checking in to see if you need more help or any clarification of my answer. If so, please reply here on this question thread.
