You want value for money. But how do you know you are going to get it? Typically, you don’t. You have to hand over the money first and then hope that everything the company said in their sales and marketing was true.
But what normally happens after you buy something?
You find out they exaggerated or outright lied about how good the product or service was in order to get you to buy it. Then you feel cheated. You might even blame yourself, thinking you should have known better.
