Was I properly fired? Will I receive unemployment benefits?

I was fired two months back for not carrying out my managers directive. I worked at a bank and he wanted me to cash a check that was not drawn off our bank and was for a non-customer. It's the banks policy not to cash checks that are not drawn off the bank and for non customers. The check was written by a customer of the bank but was not written off of our bank, but from a different bank. He wanted me to cash the check regardless then when I did so refer the person to him so he can open an account for her. When they came in to cash the check my manager was not around to open the account. The person waited for him to get back so he could open the account. I never said that I couldn't cash the check and they left on their own after waiting for my manager to come back. After the person went back to the person who wrote the check they called the bank and were upset but I was following bank policy. I feel this wasn't a proper way to fire someone but the bank can let someone go for any reason. In regards to the unemployment benefits I was denied on my original filing and filed an appeal and had the hearing today. The banks representative at the hearing stated that it is against bank policy to cash a check that is for a non customer and not drawn off the bank. Which makes me feel that I have an excellent chance on winning benefits. Any thoughts?
