Any individual poll obviously has an error margin, usually stated, and many have some political bias or other bias due to polling methods etc, plus all companies struggle to keep up with changing habits such as lack of land lines, but to simply state polls are inaccurate is very misleading. Poll aggregators that use multiple sources and weight correctly are pretty good. fivethirtyeight is the US is excellent and there are some good UK one's too like BritainElects.
You've outlined all the reasons why they're not accurate. How did you come to the conclusion that they are?
