We were in the car last week and both our phones rang within 20 secs of each other. I answered both as I was not driving and it was the same company (Tely2 was what they said) on both phones. I think that takes the biscuit. I was talking to one and asked her to hold while I answered the other. After answering the 2nd I told them to sod off as I was too busy for this.
They had taken our numbers from our answer machine.
