When I had Hathway, I liked the speed, but it would cut off my access once a day and I would have to reauthenticate. I canceled the service, but they refused to stop billing me. I thought they just had lousy customer care, but later they convinced me to sign up again, took 10k payment for a year of service and then never gave the connection, and have refused to cancel and refund. Now I am getting bills again for service I never got. I am now convinced this is a scam to get as much cash out of customers as they can before their technology becomes obsolete and the promoters cash out with whatever they can get away with.
I would strongly advice against doing any business with Hathway.
