Customer: "Hi its Mandy here from XXXXX we have a problem with a printer we purchased from you"
Me: "When did you purchase it, I'm sure it was not recently?"
Customer: "I think it was six months ago maybe longer"
Me: "Oh OK it was they way you said purchased from you as if it was the other day"
Customer: "No no, there must be something wrong with it the printing is very faint"
Me: "Er needs a new cartridge"
Customer: "Really? Its only six months old you sure its not broken?"
Me: "I'm certain"
See if you hadn't of quizzed me about when that printer was purchased I could have scammed a new one out of you.
