Fiber speed issue

Afrihost I need you to disconnect my fiber line immediately. I have experienced problems with your service from day 1, and have called your customer care line almost every week. I am tired of your inadequacy, even after upgrading from 200mbps to 1000mbps. The router you have provided me with is too slow, and even when I connect the LAN cable to my computer I still do not get the 1GB fiber line I paid for. I am switching to another ISP, and refuse to wait any longer for you to disconnect your line. I will instruct my bank to reverse my 6 month debit orders with you.
