I don't think it is the Aliens - they would not waste our time calling - they would just abduct us (they are much more advanced than calling and hanging up).
However, I am a Comcast VoIP customer and just got a call from this #... Annoying - but thanks for the tips previously posted
Don't bother trying to get call block on this number. I bought the service this morning to find out that this number can't be blocked. I hope I saved someone the trouble. I would love to know who this is wasting my time and energy.
Just wondered, has anyone been getting these calls recently had a credit card number stolen through the internet? I did and wonder if this is anyway related.
