Who called from 2136661099

I got a follow up call from orbitz, from the same person i spoke to when i originally called their 800 number.

This is Orbitz.

Orbitz called to confirm changes to my trip

Received two calls back to back from this number.  When I called it, I got a message saying that I was trying to call a non-working number.

I am trying to solve and issue with Orbitz and this phone number showed up twice on my phone. Based on the responses here it appears they use a calling center. No wonder no one can help me with my service problem.
