When I get a customer service rep like that, I don’t put up with the crap very long. I simply say “Escalate” and I get a supervisor who has more authority to make things right.
We do a lot of shopping on Amazon and have from Day One when they only sold books. They always look at our purchase record and say “Thank you for being such a GOOD customer.” That, too, goes a long way to getting the best service from them.
I was one od AMZ’s first customers when Bezoz sold only books. AMZ has expanded and now get daily deliveries for Daisy Cat and me. Delivery guys laugh that they’ll able to work forever. .
