unable to withdraw

My name is Pelthia Makgatho. I was scammed by a fake broker in the End of July beginning of August 2022. I was induced by a person via Viber named Linda with the phone number +19127070186. She got me to transfer USDT coins to Wintersnowfx and Grand Signal Markets to trade over MT5 for a total of about $8200. I was told to register first on user.gmwold.com (deposited $3000) to ERC20 Withdrawal Address : x94Bd5A010eCAD8E6d8a2f104F3102E4946CDb942 transaction ID N01255587049494221824081511, then was told they are upgrading and to register again on user.gmwoldd.com and deposited $4974 to Address 0xB623b6E6b4231840290231184740DD90b2685508 Transaction ID (TXID) 0xf6f278ff31346d0f0ff99b944dcf733d94af9700126f788032da29e35b8aaff4. She gave trading signals over bogus sites and I traded till I reached $11225.25 but now I cannot withdraw my funds. She told me they are upgrading again and to register on user.lunbgold.com and pay 20% of my deposit's value if I want to withdraw my funds. I hope you can get a clear picture of the scam progress, do let me know if you need further details. Kind regards, Pelthia
