Horrible Customer service

I signed up for Metrofibre over a month ago at the installation phase. They came and installed their cables and router. Its a month since i was supposed to be up and running but up to now nothing. I called numerous times and was advised a contractor will be sent out and they will call me back. On top of the calls i have sent numerous mails with the same response that they apologise and someone will be in contact with me. I have never been contacted and all i want now is for them to remove me from their systems because due to this i cant get fibre installed by another service provider. This is despicable i am been inconvenienced due to a company that is unable to provide customer service. I am begging please cancel my order and come and remove everything from my premises. You know absolutely nothing about customer service.
