What is the name of your state? Texas

We run a small ground transportation business in Texas and were contacted by another tranportation business from California. We performed the services needed by this other company; however, we have yet to be paid. We have made several attempts, including phone calls, faxes, email, snail mail, but no resolution. We have been told each time that payment will be made. But, obviously, we have been lied to and deceived, and continue to get the run-around. As of today, we are still trying to collect funds. Messages have been left to no satisfaction. Now, we believe the company is under new management because they answer with a new name. The dates of services/contact range from mid-April to late May. Verbal confirmation of payment was given in June by the other company. Still no payment. Is there a time limit on collections? We have a credit card on file as guarantee. Since we have not been paid, are we able to collect this balance against the credit card provided to us at time of service?
