I wonder what made you use Freewallet.org among other excellent wallets like Electrum that will never block your funds because all the control is in your hands.

Freewallet.org has been scandalous, and they have quite a number of scam accusations here.
Here are examples
- FREEWallet.org SCAM ( Don't use any of their iOS or Android APP)
- Freewallet.org is a fraudster who cheated me out of 15.2BTC
- FREEWallet.org is a SCAM
- Freewallet.org is a scam or they are just never satisfied
- Freewallet makes me stress asking me proof ID and freezing my wallet

And so many more scam accusations that i haven't listed. Their profile has already been flagged and negative tagged in this forum
Try contacting their support or this profile Freewallet and see if you still have luck. Right now you are at their mercy.
