Safe Showers, Austin Did not return the deposit after they could not carry out the work agreed upon Austin Texas

We gave the company on October 6, 2015 a $500.00 check which they deposited inmediately as deposit upon signing an agreement to remove a shower stall and install a sightly new, larger one. The salesman did not measure correctly and wrote the agreement with the incorrect measurements. When the installer arrived he told us that the measurements the company provided were incorrect and that the stall we asked and agreed for could not be installed. We cancelled the agreement and requested the deposit be returned. The office person, Kimberly, admitted their error in measurements and agreed to return the deposit via Wells Fargo Bank "billpay".  After several days again we asked about the deposit and Kimberly assured us that she had returned the deposit. To date, November 16, 2015, we have not received the $500.00 deposit or heard anything else from this company.
