COIN Less LAUNDRY

This place always have broken down machine's and today I insert a 50 dollar bill in the bill changer and it only gave me 20 dollars back and the employee that was working at the time said that there is nothing she can do about it she told that she was gonna give me a paper to Signed but she never did when I asked her for help she will take like 30 minutes to help me I think this will be the last time I come back here i didn't get the manager number or nothing i didn't even get my 30 dollars back
