Bitmask (Custodial Wallet) is holding my BTC ransom

Hi @cryptoquick im not sure you're still with Bitmask or not because I saw that you left the company to greener pasture. Bitmask has been keeping my BTC random for nearly a year.. Gideon has been saying it's because of the frontend needs connection to mempool.space API and he has no money to pay for it. How do I get back my BTC? Gideon has been saying that Bitmask is non custodial and asking me to wait but it has been months, I'm still unable to transfer out my BTC.
