Incorrect advice, poor customer service

A colleague needed a new charger for his MacBook Pro this morning. I drove over to the Cavendish iStore taking the model number and voltage details with me (photo). On return to the office I find it's the incorrect connector and the incorrect charger. So I took another hour, paid another parking fee, had my colleague not work for another hour while I came to the store again, waited in the "queue" again, and got the correct one. "We don't hold cash here", so how was I to be refunded the overcharge for the incorrect one? Well the manager was called, ("brusque" is about the kindest description) and some cash was mysteriously found. ("Mmm, now I must engage our accountants to reconfigure the purchase on our end into petty cash...") Then it was, "Do you have R1?" . Nope, afraid not. You must be joking?

"I'm so sorry, our system is incorrect" was the sum of the "make good".

This was a seriously annoying experience. - no attempt by the manager to engage at all - incorrect system (or incorrect training?) that allows wrong adapter to be given out - inability to refund the purchase without resorting to cash - fibbing about having no cash - asking for R1 change after the impact of the mistake was probably larger than the cost of the adapter itself - yes, a verbal apology, but no listening, or attempt to make good (A nice discount, or a coffee and ****in on the house for the team as some arbitrary examples, would have gone a long way and resulted in this review not being written). 1 bad experience, gets told over many time, unfortunately.

You can do better, Apple.
