No internet for 2 weeks and no assistance

Almost 14 days since I logged a call related to NO INTERNET. - ADSL I have also been paying for fibre which is yet to be connected. I have called almost every day and get the same response. I have spent hours on the phone and still no assistance. How can you be a service provider if you cannot provide a working service. Staff are unable to assist, as there systems limit what they can and cannot do.
