escalation

I need to escalate a service issue. I started internet service just over a week ago and have nonstop connections issues. Makes working from home tough. I had a technician come out today, well, now the service works worse. Connects and then disconnects constantly. The chat experience has been at best, horrible. Nothing but passing the buck. I would like to escalate this issue above the regular service techs? I spoke with an "escalation" person but he did nothing different than a regular first level service person. How do I escalate my horrible experience with the product as well as the customer service response. what am I paying for??

Strongly considering a new provider!
