I keep getting this number calling "0845 2574457" and after getting no reply so many times, I searched for it on this website with no luck.
I eventually found the number listed on  http://whocallsme.com/Phone-Number.aspx/08452574457.

It appears that this number comes from various sources and informing those who do get an answer that they are from one of the above companies.
As you can see from the link they are offering various FREE items and asking for Credit Card details.

Wouldn't it be nice to have a full directory supplied by the providers of these 0845 & 0870 numbers so we can actually find out who owns them and who do we report these scam numbers to?
