buyer requirements and bid cancellation

I am bidding on an iphone 5 case and twice I have had my bid cancelled. I cannot bid on more than one item due to buyer requirements. I have no strikes against me and it is getting near the end of the auction. What to do?

It may be the seller can not cancel the listing as there was bids and they want more than what it is going to sell for by the look of it.

So to avoid selling at a low price they are cancelling the bids.
