A frugal life is an easy life!

Firing off an email or letter in writing, can be an effective way to highlight your problems directly with a company.
Facebook groups are another way of course, but increasingly popular is the twitter complaint.

Not just another "group of moaners" using twitter is an individual's way of drawing attention to a problem that might be far more common than a company would have you believe.
Find and "follow" the company concerned, start your question/complaint with @[insert company name] and away you go.

Adding a simple #[insert twitter name] at the end of your question, reveals it in a search.
To view other people's tweets regarding the company concerned, just type #[company name] into the search bar at the top of your twitter screen.

As well as seeing your question/complaint, every other person searching for the same #[company] will also see it.
Companies would have you believe that everything is rosey on their twitter feeds, little anecdotes and the like, similar to a friend.
For a good example of how this is not the case, try searching twitter for #britishgas

In the results I got, there were people waiting in all day for calls that never came, one post/tweet revealed they had been waiting 3 weeks for a promised call back!

Although short posts/tweets are all that's allowed, a few well chosen words can be very effective!
