Complaint Review: Glencore Leads

I signed a contract for Glencore with Mark Miller to build me an email list and send out 4 monthly email campaigns for me. First off, I had to stay on top of them to get my emails blasted out for me and to give me a delivery report. When I finally received my email list I was appalled because the list contained so many emails of people who would not even be interested in my services. I specifically asked for a list of people who would be interested in math education and my list contained art, drama, physical education, and even welding instructors. The list was so bad. It even contained symbols and elements that let me know that it was a harvested list and not an opt in list. Most of the list was comprised of all the employees from specific school systems employee directories.  When I contacted Mark Miller about this list, I did not receive a reply. I was scammed $2500. I will probably never trust another email marketing service again.
