I contacted support twice in 2 years for Prime subscription I didn’t want. Each time: “Are you sure you didn— Yes I’m sure, I knew intended to avoid it, so it’s clearly not me.” Both times they correctly cancelled it.
I’ve been a heavy customer for many years. While I bemoan the rampant knock off products and fraudulent reviews, by shopping carefully I’ve actually never had a bad product delivered, and the very few times I’ve needed to call support, they’ve been super responsive and remedied the issue quickly. (Mostly refunds for digital content purchased incorrectly).
They may not be perfect, but that have that “Macdonalds” aspect now; you know what you’re getting and it’s consistently pretty good. Which is often more reassuring than trying something new.
