Who called from 4073332020

No one responded when I answered a call from 407-333-2020 (showing on caller ID)

Lake Mary, FL and 407-333-2020 appeared on caller ID.

I called the number back and received a pre-recorded msg stating the number is not in service.

I am on the DNC registry and go woken up by a dead air call odark in the morning. Its a telemarketing using a robocaller,, you get dead air while the system tries to get a telemarketer to you.

I keep blocking these numbers and filing fcc complaints. never seems to do any good.

2:25 P.M. CT on July 16, 2015: I didn't answer, they left no message.

Strange that I got a call from Lake Mary, a Florida number, my cousins just moved there and have called me from there. I wonder if they are able to get a list of incoming and out going calls to that area? Any telemarketer that calls a second time gets blocked. Just strange that telemarketer calls lately are increasing. My phone service allows 24 blocked calls but I may have to purchase a phone blocking unit to handle added calls.
