Troostwijk Auction manilulates auctions

It is a pity. Troostwijk is a big player in auctions of industrial products. But as shown at the French company, they manipulate the auctions after starting. We observe an compressor, which started with 50 EUR. But 4 days later – we don’t trust our eyes – they start with 250 EUR. Of course, Troostwijk earns more money with a higher price, but this change is criminal. But when they change starting fees, what is during the auction? There are members of the company who bid also on a product?

We have asked the company in French and also the headquater in Amsterdam, if this is normal, but we get no answer. Our trust in Troostwijk is lapsed.
