poor serveice

don't buy from them. I paid using a credit card but the transaction was not successful and I decided to do EFT when I check my statement I found that the transaction was successful and I notified them and it has been more than 2 weeks without getting my refund. They keep on asking me if the seller has refined me instead of asking the seller to send proof of payment. The order number is ***8. and Ticket IDis SYS-***3
