Home-connect is shaping my line

Firstly : Your support desk needs to be helped a bit, as when talking to them they ask me to do the same tests every few seconds after nothing has changed.

My problem was that my fiber 100/100 is very slow to any server outside of Johannesburg. When i run a speedtest to CapeTown using MySpeedTest.net I get <10 mbs downlaod and 100 mbs upload. When I run a test to London I get <2 mbs down and 15 to 20 up. But when i run a test in Johannesburg i get 100/100 what i pay for. The support desk completely over looks the first issue of Cape Town as soon as i say London, they reply we dont guarantee international speeds, As we dont have servers there. That "as we dont have servers there" doesn't make sense to me, I understand that the speed will drop due to distance and all, but not having servers doesn't make 100mbs go to 1.5mbs. Then The support desk told me it could have been the servers because i am not using my broadband. Well i told my friend to do the test he is on Rocketnet.co.za and he got 20/20 on London and 50/50 on CapeTown. He only pays for 50/50 so he is getting his service. So I then came to the conclusion that Home-Connect is in fact shaping my line against their policy with me.
