Appalling Service

Did a fibre line application on the 5/06/2023 with Vox, it is now the 20/06/2023 and I have still not been connected neither have I received the router. My apartment is fibre ready and did not require a new installation. I have been contacting them myself most of the time as the agent that was allocated with my application didn't bother herself to contact me, and wouldn't respond to any of my emails. The call centre is also a mess because you either hold on for too long or get someone who can't explain what's going on and why it is taking so long. The day the agent eventually contacted me I then asked her to get her manager to call me because I no longer wanted to deal with her as I had gone and contacted the fibre service provider contracted by Vox directly to explain why it was taking so long. The manager called me and promised to correct this. The installation was supposed to take place on the 16/06/2023, nothing happened. As usual you can never get through to the contact centre including the direct line provided by the manager, sent the manager another email yesterday, she has also now gone quiet. The fibre service provider called me to do a connection yesterday morning, I am still waiting for the router from Vox. This has got to be the worst service provider I have had to deal with. Going through other reviews gives me goosebumps because now I'm worried about what will happen once it has been fully installed. The only reason I chose Vox was because of someone who stays in the area who is using it, I have been left with a very bitter taste and don't even know what to do, who to call...
