They have been calling my daughter's cell phone late night/early morning. when you call back there's no answer. The website listed an email address.
It's probably a router in the Seattle area telecom system. There are numerous reports of this and other 206-336-72xx numbers. Some of them are from overseas callers and some from telemarketers.
I got this same call from the 206-336-7211 number. Nobody there when I answered. I called back and got a recording saying all circuits were busy. I have reported this to the FCC and would advise anyone else to do the same if you get a call from this number. This person has to be found!
I get calls from this number on my cell phone immediately after receiving a call from Burkina Faso (22650424590).
What's interesting is that the country code for Burkina Faso is 226, and in the Seattle area, most numbers begin with 206... Most of the people posting here seem to be from the Seattle area. Could it be technical/human error in connecting international calls to Burkina Faso?
