Their service is getting worse

Third day without Internet and constantly changing stories from agents. The one agent says that the line is fine and that they can reach the fibre ONT and the next one says that Frogfoot is down in the area. I have just about done everything under the sun. The first agent said that it’s the router or Ethernet cable. I change the Ethernet cable and set up a spare router with the PPPOE details and it still doesn’t work. It is beyond frustrating and their customer service and product has been steadily declining for the last few years.
