I'm going to give it the flick when my free 12 month ebay Plus subscription runs out in July. It has developed two extremely annoying traits lately.
It keeps sending me emails saying I have a security breach, they lock me out of my account and make me change my password. I haven't got a security breach. I've had to change my password ten times in the last week.
When purchasing, after logging in to Paypal to complete the purchase, it goes into a perma stall and the sale aborts.
ebay are of course useless when I ring.
What happens when you try and purchase something on another PC? I assume you've tried this, right?
