msukiwi:(One I just did - received a receipt confirmation, but not a copy of what I wrote!)
I've got into the habit of doing Select All, Copy before submitting a form; you never know whether the site's going to eat it!
My annoyance for today: I bought something a month or so ago. A couple of weeks after I received the product, they sent an email saying that I hadn't written a review of the product, and provided a link where I could do so. A week later, they've sent me another email 'complaining' that I still haven't written a review. I've paid for the thing, they've sent it to me, and the transaction is over. Leave me alone!
