Who called from 4054190400

Anyone knows who owns this phone number?

caller hung up when i answered

I got a call from thia number and I dont get any answer. When I try to call back. it says its not valid.

oh weird...I was just on hold with an ATT rep and that # called in but did not leave a message.  now, i realize, it must have been ATT.  so... i think it was ATT.

they called and i missed it. tried to call back and it was a busy tone. looked up to see if it was a number that charged you or scammed and i found this site
