Cash App complaint: Stole my stimulus and closed my account same day

My daughter’s father filed his stimulus check to be deposited into my cash app account, 5152020 it was deposited into my account which stated Deposit complete but still showed a $0.00 balance, I check my email and from cash app was a message stating the deposit was denied. I go back into my account and it still showed deposit complete, I go into support and there’s a big red! With your account was closed I emailed them to ask why, they replied back that they closed my account for SUSPICIOUS ACTIVITY and they used to their desecration that i will not be able to reverse or transfer any funds that was still in my account(blocked), I am a single mother of 4, not a drug dealer so i went into the violation codes 4-5 that they claimed i violated and can’t figure out what they’re talking about, i have screen shots of the emails, deposit COMPLETED, basically EVERYTHING!! They robbed me of funds from IRS during a freakn pandemic man!! If this isn’t resolved I’m reporting them to the IRS, calling a lawyer and obtaining a police report because i will NOT let them get away with this!! It’s actually shameful and disgusting of them and believe they use their app to scam people, and during a time like this is unbelievable!! This was the only way my family was able to send me money to help during this covid-19 pandemic… VERY DISAPPOINTED WITH CASH APP AND WON’T STOP UNTIL THEY RETURN MY MONEY
