After switching to Fidium, I went to a Spectrum store to drop off my old equipment (already cancelled service via phone). Upon entering, you're greeted by a kiosk to put in your phone number to get in line (if you don't have a phone, you're SOL). I did some shopping (this was the mall location), got a text an hour later that my turn was coming up soon. I headed back to the store, but it took another HOUR until it was actually my turn. There was a monitor showing the current line of the enxt 15-20 people to be called, but there were some people coming in who would be bumped to the front. I had no idea why. Seemingly, it's because they called first to make an appointment. There were only two poor souls working and probably 20+ angry customers sitting in the store waiting for service, just commenting to each other about how ridiculous the situation is. When I was finally called, it took possibly two minutes tops for the lady to take the equipment off my account. In retrospect, I should've mailed the equipment back.

Thank you OP, I just wish I knew this sooner! I hope your wisdom helps someone who still uses Spectrum.
