Bad sevice for new customers

I have been trying to get an existing fiber line internet connection activated since the beginning of November. The technical dept handling that was fantastic. Once it came to actual line activation it fell apart. It took Vox Telekom 10 days to send a technician with a router. When he arrived he checked everything. Said the line was still not activated and left. Numerous phone calls and emails to the relevant people have had no result. I have never in all my life experienced such bad service. I now have a fibre line. A router and nothing. Vox telekom are pathetic in their service
