Worst customer service. Made an appointment that got pushed over a week out because they "don't book inside of 7 days". But then day of, we get bumped because someone called in a "short notice" assembly, that they claimed for us they don't do.
NO notice was given to us that we would be moved not only wasting my entire morning but now my afternoon as well. Very snooty customer service rep on the other end, trying to say that 'No one was to blame'. Their entire administration staff is to blame. If you have the option, take your business elsewhere! NEVER USE THEIR SERVICE!
Thanks for nothing! How are they even still in business!?
