Celestine Q | 09-01-2021

Worst internet provider I've ever witnessed in my life. I'd prefer to have dial up internet. You pay them a ton of money, and they slow down your internet speed to coax you into paying them more money, because they are worshippers of money and only care about making life hard to gain wealth. Good thing Starlink is in my town! Goodbye permanently. Never using this service again, and would NOT recommend buying it. Go to someone else otherwise you will have a miserable time. I can't even open a browser or make a messenger call without an internet crash. After recalling my mom and my friends about 15 times I have been pushed to my limit.
