RIGGED AUCTION, ************ AND DISHONEST SELLER

I was bidding on auction number *** (Zibbedy) which was scheduled to close at 29 March 2015 20h00 hours, yesterday afternoon (29 March 2015) there was a bid which I outbid just before 16h00 and the terms on the auction were that if there are late bids the auction would extend, fair enough. Now at 19h55 there is a bid for R310.00 which when I tried to outbid it stated that I needed to input a higher value, which I did and immediately I'm outbidded reason being that this new bidder username knubby1 had a bid with an automatic bid increase each time someone bid on the item resulting in an auction bid that was at R280.00 at 19h54 to R800.00 at 20h15. I am under the impression that the auction was and is rigged by the seller in conjunction with another user, whereby they drive up the prices on goods sold under auction. I wouldn't be supprised if this knubby1 user bids on this seller's auctions and especially yesterday's auction if the sale did go through because the seller had the same item selling at the same time as the auction at R800. Can we investigate this matter as I still say and believe the auction is rigged cause at the last minute new bidder with automatic rebids.
