How not to do electronic commerce

Today, (presumably) the second instance of Mahler’s Beethoven’s 9th arrived here. It’s the first one I ordered, also at Amazon marketplace. That particular merchant first sent a confirmation for the wrong CD, and — upon my complaint — notified me that the CD was not available; the money was returned. Two weeks later — I had now ordered elsewhere, and their delivery was underway –, I received a “status message”. I responded that I considered the contract voided by the merchant, and would return any delivery from them. No response.Today, a shipping confirmation was in my e-mail, and another CD in my physical mailbox. This particular merchant will now have to pay the return postage back to them.Oh, just in case you’re wondering: I’m talking about www.germanmusicexpress.com.
