Fibre upgrade

From a very unhappy customer. I am trying now for 2 weeks to get the fibre up. I spoke to numerous call centre agents, all of them promise to handle the issue, call/mail me to give feedback. No one did...thats bad service.. I cancelled the previous fibre contract (20M), which had to be switched off on 31 July. On 1 Aug the new line (100M)was supposed to be active. The old line was only switched off 10 Aug. Now I am trying to get the new line up, we are working from home and need the fibre.
