Worst Customer Service experienced in a long time

Ordered a Fibre to home. In the comment i told them that the ONT was missing and that they needed to order one. Then the router arrives at my door, no comms on the ont. Finally after spending the whole day trying to get hold of a support agent I get some form of confirmation that it has been orderd. But I got an email saying they will bill me from the date that the router was delivered. Took 7 days after my router was delivered before had the ONT installed and the line was active.

Now I finally have have a line up and running. Which should be a 1000/500 line. I get about 500-700 on the download, but only 40-60 on the upload. Logged a ticket via whatsapp, just gets escalated, but no comms further.

Their support is a joke. I have logged online tickets that have gone unanswered since the 5 of April. Its like its a dead end, no one responds. There call center makes you wait for ages, haven't had much luck. The best so far has been the whatsapp, which asks you for all the info over and over again, then you have to wait for 20-30 min for an agent to reply, then if you miss that message by 5 min you get disconnected and have to start again. Like seriously you can see what my number is, your chat greats me by name, but I have to provide all my info every time. Technical issues exist, I get that, but your lack of communication just makes it 10 times worse.

Someone from Supersonic better phone me soon and resolve my issues, otherwise I don't see the point in continuing with this ISP
