Unprofessional customer service

I did an application on my fibre on the 22/01/2022. I received an email that my request was in progress. I am still waiting. I call regularly to follow up. they keep saying the will ask the respective co-ordinator to call me. Nobody reverts back. I took a day off from work for a scheduled appointed at 10:30am for 09/03/2022. No one pitches up. I call to investigate, I hold on for approx 30 minutes, they are investigating I'm told. Eventually I get cut off. this has happened several times. The biggest mistake is I switched over from another service provider because I was referred To as Vox as the best. It seems Vox has sub-contracted them. Vox are just as bad as you cannot speak to anyone that can give you a straight answer... Frustrated
