Query: amazon instant video is a horrible service

i have had more problems than pleasure with this service. it was fun and enjoyable at first. it no longer is. i am fast approaching having more errors pop up of different kinds when i try to play an instant video than having videos play. it is not fun, and it is not enjoyable. not only should i not have to suffer issue after issue for why amazon cannot deliver the content it promises, i should also not have to anticipate having to call customer support every time i want to watch a video
