Who called from 7045407269

I get phone calls from this number every morning @ 8:50 am.  I never answer but today I called the number back & the operator came on & said that this number has been disconnected.  How can it be disconnected when I just received a phone call??  Something fishy is going on & I will just have to block the number.  Anyone else have this problem?

Yes,  same problem and same number.  I am getting a lot of calls from all over east coast with the same results all of a sudden.

No body is on the line.
