The temp agency owes you a new check for wages earned.  If they goofed on who they gave it to, the mistake is theirs to absorb not yours.  You can do a couple of different things.  First, you can demand a replacement check.  Second, if they refuse, file a claim with the Texas Workforce Commission (which is free) for their refusal to submit your paycheck.  Third, you may want to hire an attorney to send a simple demand letter for payment.  A final option is to file a charge for theft by deception against the lady who actually took the check.
