My wife has been getting calls from 0800 numbers.  They appear to be Data or 
Fax calls because the ringtone on her Motorola is different for data and fax 
calls.  The numbers are similar but never the same.  Today for example she 
had 4 calls from 0800 915 7111, 0800 915 7112, 0800 915 7118 and 0800 915 
7119.

Anyone have any idea what or who these calls are from and how to stop them 
cos they are getting a little annoying?

TIA

Stan
