Hathway — Fraud Broadband Service

I have been using Hathway Broadband for a while. Ever since i started using their internet, it is always slow or no internet. I reported - reported and reported many times and their worst service never ever resolved. Going through another internet connection is again a big process, so i thought i will increase the speed by some extra money. I did. My previous plan was 50mbps where i was getting 5 mbps sometimes 10mbps sometimes. I upgraded to 100mbps and i am getting 10mbps and 15mbps. This is their service. I called their customer care and got connected to someone. They told me to restart the router, clear my system history and cookies and told me to go to speedtest.hathway.net and check the internet speed. Boom! internet suddenly increased to 90mbps. My mind blew away. That customer care agent asked for the ID of that speed. While i was on call, i tried to test again, thats it the speed again gone to 10mbps 7mbps... i told the agent that i tested again the speed is suddenly gone slow. Then that agent started shouting why did i retested it. I said, why what happened, she then without listening to me, said transferring the call to backend team. i was stopping her, she without listening disconnected the call. So this is what they are doing.
