My son graduates from UNCCH on Mother's Day, 5/14/...

My son graduates from UNCCH on Mother's Day, 5/14/2017. I made reservations for 8 about 2 months prior. When I called this week to confirm; they had no reservation from me. Transferred me to the Manager, who then put me on hold for 15 minutes. (I made this call on Monday @ 2pm) and they had my phone number to call me back. I couldn't wait another minute on hold, so I had to hang up. Since I didn't hear anything, I called back today and was told by the hostess that "they typically call back to confirm reservations and get a Credit Card number for insurance." She apologized no phone call was made. So no reservations! Fortunatley, I had called two restaurants a couple of months ago to reserve in the case something like this happened. I had a feeling TOTH would lose something in the cracks. No worries, we will be going to a nice French restaurant instead. Thanks TOTH.
