The Dental Enrollment Center. If you leave a message, a live sales person will call you back. You can reach them directly at 949-436-9311. I yelled at the guy for about 20 seconds until he hung up. PLEASE do me a favor and call 949-436-9311 and leave them a message telling them what you think of their illegal robo calls.
I received calls from this number yesterday and today around 4pm on my cell phone---which I rarely use, and never give out the number. This is really annoying!
