I called back number (02) 8889 4131 reached voice mail but did not say from what company.

I answered this number (as i do with all calls) - It is a call centre, setting meetings for 'Two Solar' (or so they say). I questioned the extremely poorly English Speaking 'Victim' who after about ten minutes (yep, i love wasting their time) of my questioning, ridicule and humiliation just hung up - my guess, my mobile will not get a call from these guys again.

Do yourself (and all of us) a favour, answer these calls, waste their time, make it cost them money to call us, only way to rid our society of these pestilent call centres is make them to expensive to operate.

No message left - don't recognise this number at all.
