Refund not done

Mr Price, what is going on? I have waited 2 weeks for the refund of 4 bar chairs that were purchased online but lost and then replacement found but scheduled delivery never done. I have been refunded the delivery fee but not the cost of the chairs? When I contacted your call centre I was told they don't know why it wasn't refunded and that it will now be done but I need to wait another 7 days? Order number ***, please fast track this issue. I am beyond frustrated with trying to sort this issue out.
