Bad service and bad managers

I app**** for a 10MB uncapped adsl line. Sales person told me the first month is free. I received an sms on 15 Feb 2019 that stated I would be billed pro-rata for the month of Feb 2019. The line had not even been installed yet. An appointment was made for the line to be installed on 22 Feb 2019. On 22 Feb 2019 at approximately 14h30 I phoned the call centre to ask when the technician will arrive. They could not tell me and told me to phone after 16h00 to escalate if the technician ad not arrived. I phoned after 16h00 and spoke to one of the line managers. I was told that they can send out another technician in the next week.As I had to take off from work on 22 Feb 2019, I told them I cannot take another day off. Apparently an e-mail was sent to the technical department to request a technician to come out. I was told by the line manager that she would phone me back before 18h00, as she leaves at 18h00. That never happened. I have the last 2 phone call recordings, and the appointment sms as proof.
