Not getting any feedback or assistance

I purchased an Item from an online company in south africa, which closed their business two days after i made my payment. I have not received the the goods purchased, and will definitely not receive it in future.<br> <br> After phoning absa to find out if they could reverse the payment, they sent me on a wild goose chase by sending various emails to their disputes department. <br> <br> To date, one month after my initial query, I have still not received any feedback. I've phone the credit card department, but no one can assist. All they say is to send another email to the dispute department. <br> <br> Can any one at absa assist, or should I just give up my fight and change banks?
