Trade Me withdraws listing after I had paid by Ping.

Went into my TradeMe purchases this evening and discovered that the listing for a "Buy Now" purchase from last night, using Ping, has been withdrawn by an administrator. I have had no email advice about why (maybe it was a scam listing?) nor any notification about the money I paid. I see it is "on hold" in my credit card account but I thought the TradeMe administrator would have emailed me with information about the withdrawn listing and the fact I paid (including potage) with Ping. I am presuming that the payment will not go ahead but I would have hoped that TradeMe would have given me reassurance about the money paid and why the Buy Now listing was withdrawn. Saddened at the lack of contact from TradeMe.
