Spam and no unsubscribe option

I receive a bulk email from Arenaria Training about once a month selling training. I have never subscribed and their emails do not have an unsubscribe option. This has been on going for months and I have emailed them (Prince Kharma and other employees) multiple times to remove my address from ALL future communications as I am not interested in what they are selling and I do not live in Johannesburg.<br> <br> I received 3 emails today within a few minutes. There was no reaction to several requests to unsubscribe me.<br> <br> There is no unsubscribe option at the end of the emails.<br> <br> Unacceptable marketing tactics from Arenaria Training.
