Woke me up at 4:30am calling 3 times in a row and hanging up! I could hear the hangup... not like an automated thing... sounded like a person clicking the phone to hang it up. The number comes up on an online search to a telemarketing place in LA but when you call it it says it's disconnected.
Well well....look like I have been target. The call comes in at 2:49am. I didn't answer just let it ring thinking it's a wrong number....and thinking if they knew me, they would leave a message. Didn't get a voicemail or anthing else didn't repeat to call....so I guess I'm thinkfull for that. Did the same, I simply looked up by typing in the phone number and it comes up as a telemarketing in CA....this is really weird!
I know for sure that this number is what shows up on my friend's phone bill when her mother calls from Korea. I'm sure the repeated calls could be an international caller who is trying to contact someone overseas, hence the odd hours. It is likely your numbers were reached because the caller mistyped the long sequence of digits required to go through the system.
