Disgusting Service

I am a long existing customer of Afrihost. I joined the company roughly 2 years ago, I joined when it was a lot smaller. When u joined I had nothing but great things to say exceptional service, if I had a problem i would receive help in under 24 hours and the problem would be fixed asap. Now I'm having continues issues, it took them three and a half weeks to reply to my support requests. I sent in three and got in 3 different replies, all point at the problem being it wasn't them... The modem was faulty (which I replaced), the line from Telkom was faulty (Telkom came out checked everything and NOTHING was wrong), third reply was oh your still able to download a fair amout in a full day, nothing is wrong. I haven sent back and forth 30 emails every time I get an excuse that points the problem at anything but them. I have an 8mb line uncapped, I'm virtually next door to the exchange so I get the full speed (when I don't use the line) as soon as I start to do anything on the line I immediately get throttled, the line becomes unstable and that's how it runs all day bouncing up and down from 0.2mbs to 5mbs... Up and down constantly, which makes the line unusable nothing runs, takes ages to load a page, if you go on YouTube or stream it will stream full HD for 2 seconds then to completely pixeled constantly. I have sent them tons of speed tests, showing how the graph is extremely erratic, all with the same replies... Sorry your still able to download and it must be something else (even though Telkom came out checked everything that's all perfect). No matter how many times I tell them an erratic line doesn't stop downloads they'll still run and eventually download this has nothing to do with the lines stability or how bad it is using it, no videos will load, no emails will send everything eventually crashes and fails. All I have received back is excuses and being spoke to as if I'm stupid and *********** to understand, which they don't know I studied IT and have quite a firm understand of it. Absolutely disgusting how far this company has fallen, they cannot handle the demand and the customers suffer. Something even better is not only did a person from the call center named Jason told me they're network is under strain and unfortunately they cannot handle the load I should rather get LTE from a different company if I didn't want to he throttled. The final thing is I have a friend who works at afrihost whom I cannot mention but he manages lines and told me directly the same thing that the person at the call center did, I'm being throttled they cannot handle the load. Disgusting that I've received so many lies and poor service, I will certainly be leaving and looking for a new ISP that's more focused on customer service not just about taking my money.
