Cancellation of Fibre - 1 month later no activation

3rd Review on same query. Please can you assist in cancelling my Fibre Request. I am not willing to pay for any installation or router costs. Fibre was installed in my house in the 1st week of July , but to date my line has not been activated. I have called the Call Centre 100 times and Ive even logged the call on twitter and have had no success. Please confirm once my application has been cancelled and all associated costs reversed so that I can move to another ISP.
