JPMorgan Chase & Co. Bank Account Or Service Complaint

JPMorgan Chase & Co. Bank account or service department,

Checking account Deposits and withdrawals New York

I was giving a check from my brother in law. He wanted me to deposit the check into my account. Since i know he does n't have any deposit account. Before I cash the check, i went to the person that wrote the check and make sure it was n't a fake check. Everything was good. I deposit the check into the ATM. My brother in-law sign the check, since its under his name. I did n't. A few days later i notice my account has been closed. First they accused me of FRAUD. When its not true. The check is 100 % legal. After a few days of investigation. They say they closed it due to me not signing the check as well. The owner of the check went to chase branch to face them that its okay for me to cash the check. I was n't aware i had to sign the check as well. I thought im already giving permission by depositing the check into my account. I very honorable lady. I asked them if they could give me the check back and i will sign it. I was n't aware of the signature. Im sorry of my .mistake but i did n't know i had to sign the check as well. Please help me. Im searching on possible ways to resolve this problem. im not a delinquent. That 's why im doing everything i have to do to clear my name.
