There's a familiar expression that some companies like to promote which states...."Honesty is the best policy." While I do agree that its always good to be honest in everything that you do, it isn't the sentiment of most people or organizations (even though they say it is). Companies expect you to be a honest consumer, meanwhile they do the complete opposite of what they stand for.
For instance, you are in the market to purchase automobile insurance. You do your research and finalize who is going to get your business. You give the company a call and speak to a customer representative to discuss the type of insurance you're interested in and agree on a price. A few days later, you receive a bill (or view online), not only didn't you get insured for the terms you and the representative agreed upon, but the original quoted price was doubled. You call the company fuming and the representative says "you must have given incorrect information or the terms and rates didn't apply to you". For whatever reason companies feel that its their right to deal with customers dishonestly and deceive them into thinking one way when it wasn't the case from the beginning. The scheme is all designed for companies to make more money using deception.
Tip: Never conduct business with a company that doesn't honor their advertisements or quotes you a price that was more than expected. Go shopping someplace else!
