T-mobile Home Internet Wifi Hub loses internet frequently, not reliable.

I have had the internet service for four months. A month ago, every other day i loose service i called they said restart the modem, it is frustrating, I asked for a manager, I was told that he is in a meeting, The next time that this happens again, i do not want to hear that they are new and that they are working on the towers, i will use deceptive comcast service. These companies only care about the CEOs and the investors. Customer service does not exist anymore.
