im actually in a similar situation, i purchased some items from the marketplace on the 13th of this month, now i recieved 4 of the items straight away and naturally waited from the other 6, when they didnt arrive after a full day i got worried and contacted the sellers who told me that they have a record of me making the purchase back 28th of july, now yes i did buy some things back then but not the items in question, i managed to get most of the missing items except one, of which i have been in contact with the seller about. now here is where it gets wierd ,i decided to check my transaction history on here (secondlife.com) and what do i find but the record stating that the purchse was made on the 13th so i decide to check the transaction numbers and low and behold they match the numbers on the markeplace record from the 28th of july. now i know should have been refunded the money on reciving the non-delivery notice but i have seen no refunds or had any notification about it and i am atleast 2500l$ out of pocket
