Zero Internet & Non-Existent Support – Rain Wi-Fi Failing From Day One

I signed up for Rain Wi-Fi a week ago, but the service only worked for the first two days. Since then, I have had no internet connection despite the router displaying full signal strength. When I call customer support, representatives tell me the router shows as "offline" on their system. Every single agent promises that the "Advanced Team" will contact me to resolve it, yet no one ever calls back. I have been calling daily with zero progress or accountability. At this point, I am questioning whether this "Advanced Team" even exists. I am paying for a service I cannot use. I need a manager or senior technician to contact me immediately and resolve this connectivity issue today, or process my account cancellation.
