Vox Teleecom White River poor service

I app**** for Fibre and they took two weeks to install. Then 23rd Feb they said they activated the service. I was told I'll get an email for a password I got a password the following day but each time I apply the password is incorrect. They have a 24 hour service I spent the whole day on Sunday 25th sending emails calling and sending whatsapp till today 7 days later I still have not been able to get a password. They sent another password and I was promised calls and a technician to look at my problem and I. Still without a password and no Fibre. To my surprise I got an invoice today to pay for a service I did not use. They are also billing me for the new month. I spoke to Etiene and I have not been helped I asked numerous times for a person I can escalate the issue till now I don't have a number of his manager or the owner. This service is shocking and appealing and why they want me to pay for a service I have not used. I did not choose to not use the service but their incompetence and empty promises led me to this. I also asked for a cancelation and Etienne told me I will have to pay for a cancelation fee. Why am I paying for their incompetence and unkempt promises
