Freewallet has been around for some time, and so has its reputation. In the past, there have been many victims like you. if you look for it in this thread, you will probably get quite a several accusations for the wallet.
if you look at the forum representative account, you can see the tags and flags there. it is a warning. why not withdraw your assets from the wallet earlier?
occasionally their representative account is active. but it looks like he's been inactive for quite a while. if you want to give it a try, you can proceed by sending them a PM. but I doubt it will solve your problem.
