You cant take it down once bids are placed, You will need to refund the winner back their credits and depending on how the winner feels about you putting the phone on here and then selling it well that was kind of low so yea you might get negative feedback because its not very nice to do that to someone. Once you auction something you should stick with it and this isn't good seller status for you if you want people on here to trust you as a seller.
To make sure you get the most bids and credits from your listings, please add more information about your item. Details such as make, model number, condition, and any known issues will really help you get more credits. This also reduces the number of questions that your bidders have to ask.
For the best possible results, you should also post a clear, close-up picture of the item in your possession instead of using a stock photo (a commercial photo taken by the manufacturer). We recommend photos of your item powered on, powered off, and of the back and sides. All of the pictures should be taken on the same background. We also highly recommended writing your Listia username on a piece of paper showing it next to your item. Doing so will help bidders know that you really have the item in your possession.
All of this will prevent your listing from getting flagged. The last thing we want is for your listing to get deleted!
Thanks for your cooperation and hope you hit the jackpot with this listing!
