Problems with Ebay  

I usually make a little extra money selling items on Ebay. Car parts & other things. I listed an item on Monday morning and when I wen to check it in the evening, Ebay had cancelled it because the buyer's account had been compromised. I listed the item again that same nite and when I checked it Tuesday am it had sold thru the Buy It Now feature. Ebay has a little box that you check off when you are entering a listing that says to check if you would like to block potential problematic buyers for example members with a -1 rating or lower (I didn't think that was even possible) and those who have had 2 or more non payments in the last month. Well low and behold the person who bought it Monday nite has a -3 rating with a private feedback. Needless to say I have not received payment and when I tried to file an unpaid dispute with Ebay it says that I can't until after February 19. I sent the "buyer" and invoice and a message to pay or I will report. Of course no answer. I also sent Ebay a message in regards to the so called block of those with a -1 or lower rating and I have not heard back except for the automated "Your message is very important to us and we will contact you as soon as possible". I have been using Ebay for 3 years now and this is by far the most frustrating thing to happen. I basically have to sit and wait. Has anyone had any issue similar to mine? If so what was the ultimate outcome?
