How to lose a customer for life, Part 1

Make a claim that you have the answers.
Stake out your space in the customer's mindscape as the store in your particular category that has customer service.
Never mind that you're everywhere and your brand is known and, ahem, loved. You have spent years now being the store where questions are answered.
Then, hire salespeople who are poorly compensated and have to get lucky to really make a living. Express to them that they have the answers... do they train these kids? I doubt it.
Then, sell a warranteed product (with a known name brand).
Make the rebate process atrocious.
Offer the customer a warranty program that essentially duplicates the one the manufacturer offers. Neglect to tell the customer that you aren't going to honor that first guarantee.
Tell her this when the $350 product she has purchased breaks within the warranty period.
Do so over speakerphone, all the while failing to apologize.
Wonder why online retailers, Best Buy, Walmart and even the pathetic CompUSA are kicking your ever-loving ass in the category you invented.
Welcome to RadioShack hell.
Avoid at all costs.
