This company is horrible I made an appointment online for 10am at 6am at about 7 I got an email saying that they hate I couldn't make the appointment and then I received a phone call to say they cancelled it because it was taken and I could be a walk in. So I asked why would it let me make the appointment if it was taken and I was told I should have scheduled it a day in advance. After speaking to Grace at corporate headquarters she was no help and acted as if it was my problem not hers.
