Please exercise patience,
this doesn't happen very often and while it does I understand how it can be frustrating. It is a maintenance issue and you all should know that sometimes things fail and it can take some time to locate and fix the problem. This is no reason to threaten to go to some other bid sniping because Auction Sniper is the best and easiest I have used and they care about their customers and will help you with any problems without fail. Just write them in the proper format and see. 
So please be patient with them and stay with them. If you need to snipe a bid while system is down. Go to another free sniper site that will allow you a free trial and use them for the time being so that you can win your item.
Then you will see why patience with Auction Sniper is well worth it.
And NO I am not being paid by Auction Sniper...I just happen to have been in your same boat once before and I tried others and I love Auction Sniper best of all and will NEVER go to another snip site! I will sit back and wait. Thank you for your understanding and patience. Best Angel Wishes to everyone!
