Struggling with inconsistent service

Ever since January 2016, I've had issues with my speeds. I am on a 4Mbps package and in general it struggled to get past 3Mbps for 90% of the time for January.<br> <br> For one whole week, the speeds were around 0.5Mbps, and they did repair an issue between their stations; however after that my speeds averaged 2.5Mbps.<br> <br> I decided to cancel my subscription and asked that the 30 Days notice period be wavered as they cannot provide the service I am paying for; namely 4Mbps.<br> <br> It has been 2.5 weeks, and i have not received any feedback.
