My dd placed a winning bid on an item I don't want.

I've installed the app on iPad, dd was playing on it and unbeknownst to me placed a bid (it said I'd won the item but seems more like a Buy It Now) on a shitty item from a seller in China which comes to £10 including postage. I don't want it! I've messaged to seller twice to ask if I can cancel it but have not heard anything back (I don't know how good their English will be).
Where do I stand? Can I contact eBay about it?

I didn't pay, and as I said up there the seller messaged me back. The purchase has been cancelled . All sorted.

That's great. And easy done. My dc2 bought 2 toy kitchens via the Amazon app a couple of years ago when she was just 3. We were on holiday, and she said she said she missed her one at home. Luckily I was able to cancel both (after an anxious wait for the second cancellation to be confirmed, I'd resigned myself that at least my niece would have a cracker of a gift that year!). The purchases were password protected too, but she was obviously sneaker than I'd given her credit for. I've since changed my password to something stronger!

something of a child prodigy!

I think the problem with iPads are the security settings for apps are limited and you can't set profiles - one for you and one for her. Just double check as there is the odd app you can disable. Otherwise security is going to have to come from within the app - there must be a tick to turn off "Keep Logged In"?
