They scammed me and ask me for more money to be able to withdraw and I don't have it

Hello, my name is Omar Montes and I am from Mexico. First, they contacted me on WhatsApp and gave me simple tasks rating places, then they asked me for a deposit of 300 so that later they would return 450, which did happen, then they asked me for another thousand, after that 3150, and in the end 7460, at which I did what I could and deposited it, this money was going to cryptocurrencies, but by mistake I put it in a different one than the one they told me, and now they are asking me for 18k that I clearly can't get because I don't work to be able to recover the frozen money. They gave me a deadline today at 8 pm :(

The following is the original recommendation

Me estafaron y me piden más dinero para poder retirar y no lo tengo

Hola, me llamo Omar Montes y soy de México. Primero me contactaron por WhatsApp y me dieron tareas sencillas calificando lugares, después me pidieron un deposito de 300 para que después me regresan 450, lo cual si sucedió, después me pidieron otros mil, después de eso 3150, y al final 7460, a lo cual hice lo que pude y lo deposité, este dinero se iba a criptomonedas, pero por error le puse a otra diferente a la que me dijeron, y ahora me están pidiendo 18k que claramente no puedo conseguir porque no trabajo para poder recuperar el dinero congelado. Me dieron fecha límite hoy a las 8pm :(
