Who called from 4694690000

Called me two days in a row early morning while I was asleep. Woke me up, but by the time I woke up it was a missed call. Tried calling back but number was disconnected. Decided to block number

keep getting the same calls...just block the number thats what i did

I have had the same thing happen twice. What is it?

I like to know how it can call us and i call it back and it not in service...lol

They've called me for 2 days now and I didn't answer.  they don't leave a voice message.  maybe if they left a message people would call them back even if it is United Healthcare
