Amazon Sellers' Accounts Suspending Payments Nationwide

I have had an Amazon sellers' account which I used only infrequently, usually to sell DVDs.  I always shipped out purchased items by UPS, even though it cost me more than Amazon allowed because I wanted to make sure my customers were satified with their items on receipt.  I had never had a charge back, or demand for any refund, and had never been notified by Amazon that I had ever violated any policy of Amazon.  Recently, I decided to sell my DSLR camera body and a couple lenses I didn't use often to come up with enough to upgrade the camera body.  I listed each item for sale on my seller's account, and the only response from Amazon was to confirm a succesful listing for each item.

But when I received purchase orders totalling nearly $2,000, THEN Amazon notified me they were "suspending" my seller's account and would "suspend" payments from my account for 90 days.  I went online and clicked on the link to see the actual notification.  There was nothing about past customer complaints, no mention of an specific policy I had violated, but there was a lot of information containing "sales metrics" which were zero for quite a few months back (since I hadn't used my account).

I told Amazon that if I wasn't going to be paid upon the customer's receipt and acceptance of the item, I was not going to ship.  I also told them that I would ship WITHIN THE HOUR upon confirmation that payment would not be suspended.

Amazon's response was to REVOKE my seller's account, and any future accounts I might try to open.  I can only surmise this was an attempt on Amazon's part to hold, and use, my money for 90 days before sending it to me.  Otherwise, they could have told me my account was suspended when I began to list the items for sale (which they didn't).  They couldn't do this to the big third-party retail sellers like BestBuy or Adorama, but for the individual, occasional seller, I guess it was worth a try.

Their conduct was bad faith.
