Worst Customer Experience

What we thought would be a new relationship and happy interaction as we signed up for a new fibre installation, has now turned out to be the worse thing we ever did. The company does not answer their calls and when you get through you are promised to be called back or your issue will be escalated and nothing happens. It has been over 30 days and installation was done 2 weeks ago and we were promised that within 21 days all will be active. We are ready to cancel our request but cannot even get assistance with that and debit order was triggered but no service.
