Slow or no internet and no response from logging support query

Jenny Internet is a terrible ISP. You are locked in by paying a large upfront capital installation fee. You have an internet connection about 50% of the time, but then it is impossibly slow. I have a 4 Mbps that burst to 8 Mbps uncapped connection. I rarely reach 1 Mbps (in cases where there is actually a connection). I have logged so many support queries on their website and I have not received a single response.
