Afrihost fibre ****

Got a 50Mps octotel fibre line from Afrihost, i only got 50Mps for the first few days then it was dropped to 35Mps after numerous back and forth and testing they insist i am not being throttled to 35Mps even though my ping remains between 1 and 2 and i am still paying for the 50Mps, I feel like i am being ****med. Worst Isp.
