Sorry to hear of your not so good experience.
From what I'm seeing there is more sats and network development to be done to " equalize " the numerous different service offerings.
Equalize - I mean by, getting all services to a decent stable QOS level. Currently mobile/RV users are experiencing slower speeds than normal.
Speeds and reliability are expected to increase as Starlink teams make developments.
Whilst I acknowledge your stress and the inability to use the connection at certain times - But hold on, its worth it - The end result from the great team at SpaceX is worth it, the impossible is made " late " with SpaceX but they do things pretty well. Given time and bug fixes, firmware updates you should see normal stable internet within the next few weeks ( maybe a month or two depending on how launches and firmware updates go )
