support assist

Support assist is basically useless. Had to delete it from system, then reinstall it and it worked. Try it again a week or so later and it just won't work. delete from system, works ok....Then around we go. This has been an ongoing problem since I purchased this Dell computer. No use contacting Dell. There appears to be no solution other than, well,  when it hangs up and tells you to restart the computer which doesn't help. 

Does ANYONE at Dell have ANY idea why this happens? From what I've read this is ongoing for everyone. Very poor service, indeed.
