We came to cancel service as well as return the modem, we've been trying to cancel service for a while and due to my mother losing her account password/security question & answers we were not able to get it done over the phone. We've requested a temporary pass code to be mailed to us and was told we should get it in about a week. 1 week later, pass code still not received, so we decided to just go in person. Office is located in the downtown area, our only parking options are street meter or parking lot that charges an arm and a leg per 30 minutes. There is no parking validation, and finding street parking in downtown is like trying to win the lottery, so no choice but to pay the parking lot the ridiculous amount they charge for the time we were there.

Reasons she wanted to cancel service:
1) When the WiFi does work it's sometimes slow as hell (max speed I've seen was about 30mbps, when I called about that the agent said "can deliver up to 50mbps, does not guarantee the speed will always be at 50mbps, sometimes may drop below half speed during network congestion" all I got to say about that is "no way in hell we experience network congestion 24/7")
2) Some days, even though the WiFi was connected, I wasn't able to access the Internet (YouTube, Web pages, images, FB, etc. Tried everything and nothing loaded) I've tried to help my mother figure out what was not working, I've reset the modem, unplugged all the wires, disconnected everything, but nothing worked. Even when I called about the problem and have the agents reset the modem/network on their side it didn't do anything to fix the problem, the agent told me that they don't see any issues on their side. Um... What the hell? If there's no issue, why isn't it working on any of the devices I've tried to test the connection with?
3) The price for service keeps going up. My mother used the same service for the last 3 years, haven't added anything to it, but the prices just keep going higher, went from $30/month (Internet 50 maps + modem rental) to $42/month, then $54/month and last bill I saw when my mother said she wants to cancel service it stated $117/month. At first I thought "that can't be right, it clearly doubled the last bill, maybe she forgot to pay last month and was charged 2 months of service + late fee?" So I took the bill and throughly read the entire thing (fine print included) and found out that my mother did NOT forget to pay the previous month, the price went up so high because her "promotional discount rate" had expired so she was charged the regular rate. I had to do a double take because I couldn't believe my eyes, $100+/month for slow WiFi that rarely works right, and it's not even one of those "Fiber" high speed Internet that promises to deliver speeds up to 100-300mbps. Ridiculous. Clearly trying to rip us off, because even Spectrum don't charge that much for internet service.

So we decided to just upgrad our phone plans to unlimited data with hotspot, and cancel this B.S.
