I tried to call in at 4:45 knowing that it closed at 5. I just had a simple question to ask. They answered and put me on hold very unprofessionally. i waited and waited and eventually hung up. I then realized it was closing time at 5 and called at 5:05 when i got off the phone. All i could is the operator to say it was closed. They put me on hold just because they didn't want to do their job. WOW!
