Devastated pensioner

Account manager at Villion promised me that my funds would be paid into my bank account within 24hours after I had arranged to close my account with Villion. The funds were cleared from my Villion account. Then they informed me that it is in a wallet with blockchain.com and I have to put 75% of that total down - a mirror transaction - to proof I'm liquid and not a money launderer. After what I had put in to be able to close the account, I am not liquid anymore. I do not know what to do.
