Bad Service / Bad communication

We had a ADSL line for years. Mweb keep phoning us to change to fibre, we decided to go for it. This includes free installation and a rooter. The fibre was instaĺled Saturday 20 February, they were suppose to do this 8h00 but only arrived 9h30. The guy said they will deliver the rooter in 24 hours. We are still waiting and the ADSL line does not work anymore. We run a business with no wifi, if you phone you hold on for ever. The guy said he will let the correct person phone me back, I am still waiting. This is not good service at all, but the new account was already send to us? Going to fibre was obviously a bad choice
