Bad service

Having a problem with my ESET SECURITY ULTIMATE I tried to resolve this matter with ESET without any success for weeks now. If you don't contact the guy at ESET Vuyisa Sobili then he doesn't come back to you. The issue is with the VPN CODE, it seems they can not give me the code, even when I told them I did not receive the activation code. I reinstalled the VPN over and over again with the hope I will receive the code. All a waste of time. I even send them a message on Facebook, they didn't even comeback to me, absolute no service at all. Vuyisa Sobili have all my emails on record… It seems they can not figure out the problem, then I'm wondering how on earth can they resolve and protect my computer against attacks ?
