If you did the work, they have to pay you. If they won't, then you may sue them for the money they owe you--unfortunately that is the only way to get your money, or even to make sure they respond if they won't even answer your question. Fortunately though, you have the option of representing yourself (not hiring an attorney)--called being pro se--especially if you sue in small claims court, where the rules are somewhat relaxed and the procedure informal. That allows you to save on legal fees and expenses, which can make bringing a lawsuit for a few hundred dollars costs effective.So, to sum up: you have a right to the money, but if the employer won't honor its obligations voluntarily, the only way to make them do so if by a lawsuit. Good luck.
