Problem with Dell, HP, Lenovo -> ship it back and pray
Problem with Apple -> walk into covent garden and ask.
My experiences with Apple support has been nothing except glowing. (Apart from one work incident where our IT supplier ordered Applecare (3 years service warranty) instead of Applecare+ (2 year accidental damage) - and my employee dropped his laptop).
I got given a Patagonia bag (not my thing), the wheel broke off (thanks AA), took it to a store, and the customer service was so good I’m a convert. Conversely, I recently stopped using a service I spent >$20k a year on because their customer service was so bad. Can you boost profitability short term? Definitely, but I suspect in the long term you trading long term customer NPV for short term profits
