I am wondering if there is a technical issue. For the past six or seven items I have bought off eBay, I have not received any feedback from the sellers. If it was just one or two, I'd not worry, but it does seem odd that a whole bunch in a row haven't left feedback. This must be a technical issue, surely? 

Has anybody else experienced this and, if so, how can we get the people at eBay to fix it?
