Supersonic the worst no service

I ordered my router on the 25 November and after 5 days I called and told me they couldn't see the payment I made. Then they promised delivery the following week. 15 days after and after many calls the router finally arrived. I tried to connect but failed. I called and they kept on saying a technician will call me back to no avail I waited. Then I sent a message via messenger then they said the sim card was not activated they need documents to activate. I sent the documents and even today on the 3rd of January the router is still not working. This is the worst company and I need to cancel this service without penalties since they failed to keep their promises.
