Spam and more spam

I have a very similar story. Before Christmas 2014 I made several phone calls to them (at my own expense, from Cape Town) and the lady said that I and everyone else at my organisation were removed from all their mailing lists. Then in late January their mails started up again..... part of the problem is that they have so many different mailing addresses (probably each with their own copy of the list). <br> I have never worked with this organisation and DEFINITELY WOULD NOT TOUCH THEM IN FUTURE AS THEY ARE CLEARLY SO UNPROFESSIONAL!
