My customer uttered me a worthless check for a service provided under the guidlines of a contractual agreement

I provided videography service to a dance school. The service was aggreed upon by way of a contract. The total charges were $1,275.00. The customer(owner of the the school) made two deposites totaling 600.00. The balance was
$675.00 due at the time the video was issued. On Aug 15, 2009 an exhange was made. We gave the customer the video plus 24 additional copies, the customer gave us a check for $675.00. Myself and the customer utilize the same bank (Sun Trust), so I attempted to deposite the check, I arrived at the bank less than one hour after I received the check, however I was informed that the check was non negotiable due to insufficient funds. When we contacted the school's owner she had her rep tell us the video had problems and we will the owner call you about the bad ch - Is this your question? Add additional information
