First, please remove the merchant's name from your post so that you don't get in trouble wih the forum moderators for violating Community Guidelines.

Merchants have no control over delivery from Marketplace.  That is all handled by Linden Lab's Marketplace software, part of the service for which a merchant pays a 5% fee on each sale.  Unfortunately, delivery failures are fairly common, especially when orders are placed from a shopping cart instead of being placed individually with the Buy Now button.  You have done the correct thing so far by contacting the merchant for a redelivery. If you have tried several times and had no luck, submit a support ticket to LL under the category Marketplace Issue >>> Failed Marketplace Delivery.  Include all details of your transaction, copied from your Order History in Marketplace.

Not sure it's a problem mentioning the names like this, is it? The OP isn't accussing them of anything, just asking what can be done if they can't be contacted.

Which is, of course, nothing unless LL come through.

It's a gray area. This is "personal dispute", since there is no TOS violation involved. Community Guidelines prohibit personal disputes here, so one way to make it impersonal is to remove the name.
