What legal help can I get with a felony case pending I believe to be is wrong ?

I went to lease a vehicle and sales let me leave with the vehicle upon approval. Since the lease was never approved the vehicle was reported stolen and from there an arrest was made and I was detained. With the charges pending since July I have been unstablized going through financial hardship and won’t be able to work in my profession until it’s clear. I believe they just shouldn’t have let me leave with the vehicle and I wouldn’t be in this situation. I can give more details if this is something I can get help with.
