Not Responding

My internet went down Last thursday (19th February). I know that sometimes things get out of sync with the DNS, so I attempted power cycling my router a few times to see if it would refresh the connection but it did not. The next day I contacted their support, my internet was still down. They requested that I power cycle the router, resynced the connection and nothing helped. They have now gone silent and are ignoring me. Horrible service, nobody seems to know what the problem is and Afrihost doesn't care. It will probably be quicker for me to cancel with Afrihost and sign up with someone else instead.
