Supersonic - I cancelld twice with them before I even got Fibre

When did you try to give a business a second chance, because you're a nice person, after they disappointed you the first time (yes I know - I should not have expected anything else). This happened with supersonic Fibre. I ordered the 20/20 with them in May. They tell you it takes 7 to 14 business days. As I've learned the hard way with other service suppliers, ignore 7 and just get ready for 14... So, on day 14, after receiving the same "Your new order is still in process...." e-mail every second day with nothing really happening, I cancelled. So, I tried again a month later. I specifically told them that I cancelled before, thinking that it would be high priority this time. After 7 days I contacted them on their WhatsApp line. After initial contact, the agent told me that he needs to transfer me to another agent. It was quiet, I rep**** "Hello", 10 minutes later I rep**** again with "someone there?" - an hour and a half later, there was a response. Two days later I just cancelled again. I don't know if they only have 3 employees, or what the hell is going on there. Now, trying to get another ISP, supersonic still hasn't opened my fibre line for someone else to give me Fibre. I told the agent that phoned me to hear why I am cancelling, that this must be from management side. This can ONLY be due to the either bad or lazy or I-don't-care attitudes from someone above. I know two people who use Mind-The-Speed - they got their routers within a week. In one case, my friend had fibre within 72 hours after the initial payment of the Activation fee. I was happy with Axxess and Cool_Ideas. But SuperSonic have given me the worst service in the last 3 years of having Fibre. And the rest of the reviews on HelloPeter doesn't look too good for them either.... My only problem is the poor people working for them. How long will supersonic still have custoemrs, before their staff have to look for other work because no one uses SuperSonic any more?
