'Out of area' ID, no message. Called and got recorded greeting "Thank you for calling GT3 Telecom" - hung up.

asked for christina white -- there has never been anyone by that name with my number.  then they call and ask for amanda grey or nathan black..............really cant they get more original than that....

Received numerous calls from this #.
Answered once and told them my # on do not call registry.

Hung up on me
No more calls after that

Called my cell phone, It shows Ontario, Canada.  I did not answer and they did not left message.....
