Had a call from this number today. I've been getting calls from unrecognised numbers 015-170-32754 015-547-8404
0 all week. I'm on O2 and my contract is 12 months old, even though I'm on an 18 month contract I have a feeling these are phone related. I rang this one back as I thought it may be someone I knew who had a new number and it was a 3 message box which was full. I don't know anybody who has a 3 phone. I think it's the same people trying new tricks.
