SORRY MISTAKE WITH INVENTORY.... CAN I HAVE MY REFUND PLEASE

Twice I have order stock that is available online only to be advised weeks later it is not and they made a mistake with their inventory and you will be refunded. The first refund eventually came in and I am now awaiting the second. They screen print their records REFUNDED but the money is NOT YET IN MY BANK!!! I get apologies for the error AGAIN and here is 10% off your next purchase.... where is the 10%???? And then when I look through the stock I am wanting... there are all the baskets I have previously ordered with IN STOCK but they do not have it. Something is very wrong here. It is false advertising and I am getting sick of always trusting them, waiting months and then fighting for a refund. Shocking!
