Vox fibre installation

I pre order fibre with Vox in October, the line only got I stalled December due to a delay in the area going live I have since been contacting my sales person Dirk who failed to mention he was leaving and never did anything to get us up and running I've been phone them since before Christmas and I keep hearing they going to open a ticket and a technician will contact me. Since before Christmas up till today still no technician as contacted me and when logging into the customer portal no ticket has been opened the service I have been receiving from vox is putrid and unacceptable a d they have not even activated out Internet I am at my whitts end trying to get a hold of a Tyson who is supposed to be a lead technician to come and install the number given to me just rings and No1 answers I would like my vox cancelled and going with another isp because this service it's unacceptable
