Sucks that you ran into such shady people. Im not an attorney but it seems to me that not being approved by the 245i was the best thing that happened to you.
This is because in order to qualify for DACA, you have to have no prior legal status. If you had been approved by 245i,and i dont know if that would have given you lawful status, you wouldnt have qualified for DACA.
Congrats on qualifying for DACA, its not a permanent solution, but more of a chance and we have all been asking for that.
I really think that if you do get approved by DACA, since we still dont receive any type of legal status, you should just do what you can with this opportunity.
This is get your ID, DL, a job, maybe go back to school.
The 245i seems to me like a boat that sailed away...but Im not a lawyer and your other route would be contacting another lawyer, but an honest one this time.
Good luck and welcome to the forum.
