Who called from 6504750880

No voice message. When I called back I got a message saying I'd "reached the customer support center" and that I should leave a message for callback. Obviously spam. Adding it to my blocked call list.

Just got a call from there with no one on the other line!

Received call from this number on my cell phone....no message left, no one on line when answered.

Missed call on my cell - No message left?
