HELP! I am caught in a SCAM. :(

[luvbytes29]

I purchased a clock from an ebay  seller and received it.  About a month later I receive a letter from the Bradford Exchange saying I owe them $300 for a clock they sent me.  I reached out to the seller who said he was clueless and that it must be a scam.  After recently receiving my 2nd non payment notice I contacted the Bradford Exchange who informed me that the clock was purchased and shipped but then a charge back (?) was made where the money was refunded to the person who purchased the clock.  I have no idea how to proceed with this and the B.E. said that the letters will continue to come to my home until the issue is resolved.  Any help or advice will be greatly appreciated. 

He has another clock listed here:

If this is a case of triangulation, the eBay seller (or possibly the drop shipper the seller contracted to fulfill the order) may be in turn placing orders through a legitimate clock company to ship the item direct to the eBay buyer. If the eBay price is lower than the manufacturer's price, possibly the payment is made using a credit card which is later disputed.

Accounts involved in triangulation scams tend to be new accounts with little or no feedback for selling that offer low cost deals on common in-demand items -- often such deals are too good to be true, since the scammer does not have to pay for any inventory, and the scammer wants to encourage as many transactions as possible very quickly, as the scammer expects the account to be caught and terminated soon.
