Continuing calls from this number to my mobile and home phone from a guy names 'James' from a company he says is called 'End to End'. No matter what I say, they have kept calling back several times a day for the past 3 weeks. Both my numbers have been listed on the 'Do Not Call' register for many years now. When I say "Please don't call me back" he always just hangs up abruptly. They keep calling back.
