I have been getting 2 or 3 calls to my mobile from +44 131 5531100 for the last few weeks. The first time I received a call I was suspicious and wary enough not to answer and I haven’t answered any of the calls since as the caller never leaves a voice-mail! It’s all getting rather annoying.
I did some googling on the number and after reading this post (and the comments that follow it), I am very glad that didn’t answer the calls!
I have the number diverting to my voicemail as I can’t directly block numbers on my mobile.
If you start to get calls from this number it is up to you whether you answer and engage, but before you do make sure to do some research and read the above article first!
