Next day delivery.. you pay, it ships, then delivery estimate gets an "oops you're delivery had a problem and has been rescheduled for 6 weeks in the future".
Can't refund as it has been shipped, and the original listing disappears after a couple of days "listing not found", so no feedback possible either.
You'd think that a consistent customer would be worth more than $30, but apparently not to Amazon. They wouldn't make it right so I shop elsewhere now.
If you have prime, talk to customer support until you get the answer you want to hear. In general, they have been extremely supportive of all the various issues I've run across, but then again, I buy a lot of stuff from there.
But generally, frequent customers at any shop, get better service.
Then again, there is costco too. That is a paid membership for support.
Resolving a situation where a different, cheap, unusable item is delivered is absolute basic customer service which was paid for when GP bought it, regardless of how frequent/premium of a customer they are.
You can't shop at costco without being a member, I don't see how that's related.
