Afrihost - don't give a damn...

It is a pity I have to give them one star... Afrihost offered me a internet package after I was recommended to call them. Everything was seamless, quick. When I plugged the router in at home, which they had configured my trouble started. It took 8 hours to down load an eighteen gig update! I called repeatedly over a tree day period, sent mails, sent whatsapp, posted on their facbook page - begged for help. NOTHING. I wanted to speak to a manager, some staff "posed" as a manager, they admitted that after they were caught out. After 4 days i unplugged the router, it simply did not work I was told to reboot it every two hours over the next 3 - 4 days. After numerous promises that a manager would call me to resolve this I gave up. It never happened. Now they charged me for a service that is poor, poor , poor. How do I get my money back. ICASA? I saw on line there were many complaints. But they actually don't care. Sad thing is they came highly recommended from one of their clients.
