4 Weeks and still waiting for my refund!!!!

I purchased an item on the 12th of Sept. The item was out of stock and requested a refund. I am still waiting for my refund. Every time I contact them its a lame excuse and said it will be processed. Please resolve this ASAP.<br> <br> Payment receipt: 100000140<br> Ticket Number: 3346<br> <br> Regards,
