Hi PDCool.
No I have not, I have not had the greatest experience dealing with you from getting my line installed to dealing with account related issues. So I am pretty ready to throw in the towel. My line is set to be cancelled on the 31st of December 2018.
But if you can get my international line speed sorted then I might reconsider. I dont get how the problem could lie at octotel since they are only a last mile provider and my local speedtests are fine at 100mb/down and 25up. This means the last mile that Octotel provides is working as it should and points the finger to the ISP. My speeds also slow down in peak times (evenings) when everyone uses the international links.
