EBay payment help! Will eBay charge me automatically for this?

So I won two auctions for two different iPhone's on eBay, and I decided I didn't want either of the iPhone's. It has been 2 days since I won the auctions. And so I just contacted the two sellers a few hours of wining the auctions. I told them to cancel my order and to apologize to them. One never responded, and the other kept asking me why I bid and all these questions.

So anyways, apparently eBay saved my debit card, for a "Reimbursement payment method" which I had no clue about. And I have no way of taking the debit card off. They won't let me. So will they charge me automatically for the items?

I'm so worried about this, because I can't afford it! Please please please help!

No, they won't, but it's up to you to withdraw your bids. You also could go to ebay communities to get answers to questions like this. And as you see, it's really dumb to bid on things that you don't intend to buy.
