Who called from 6041498367

Got a phone call. Picked up nothing there and they hung up

They called. No one on the line. Just dead air.

Dead air when I answered, then someone picked up. Very poor reception on the line and sounded like there was a significant delay. Asked to speak to the owner of our company and said that it was CNK Canada? Something to do with missing kids?

Called with an overseas prefix, noisy call, just hung up after being answered.

604-189-4367 called my DO-NOT-CALL number at 9:27 Pacific on February 19.
604-149-8367 called the same number at 11:37 Pacific on March 4.

Curious "transposition" of numbers ?!

I picked-up after 2nd ring, but nobody answered.  After 30 seconds, they disconnected.
