Called me lots before so I blocked them,now they call me from 60 4 606 7888, don't know how they managed to put a space in between the numbers but very sneaky!
My fiancee and I got calls from this number and got pretty aggrevated because we hate spam calls. I called the number back and noticed it was Times Telecom but this was not a "junk call".
We picked up the 4th call and found out it was my fiancee's mother calling from L.A. It was her mom that was calling from a Times Telecom calling card...so no worries for me. Not sure if this applies to you but maybe try picking up and seeing who it is next time.
