They let me use multiple coupons at once (all expired and all say that you can only do 1 discount).
For the account info:
The service tech checked my account and confirmed that only my contact information is on my account and printed it out for me. Then the other tech asked if he checked the scheduler? And they found the ex's contact information on the scheduler. He updated the information on the scheduler and then they both logged in on different computers to check, including scheduling an appointment for me to confirm that only my contact info is on there. Then the other tech checked again and confirmed that it was correct on his computer.
