Cellc fiber horrible company

This is now my third complaint on Hellopeter regarding the same issue. I had my fiber line installed through blitz fiber on the 19th of June and my ISP through cellc fiber. From the 1st day I have had issues connecting and when finally connected I have had numerous disconnections and even now my router is lit with red lights unable to connect. Speeds on a 50/50 line is no more than 5mbps. Blitz fiber says the reason for this is because cellc was struggling to get any customers connected in PE, because of routing issues. I want this contract to be canceled as it has not been 7 days and I am protected by the CPA otherwise I will be forced to lodge a complaint with ISPA against cellc fiber. Why do you think that you can sell a product to a customer which he cannot use? Please have someone other than a social media representative call me preferably someone at management or cancellations. I want this resolved today please.
