TOOK MY MONEY, CANCELLED MY ORDER BECAUSE NO STOCK AVAILABLE AND HAVE TO WAIT 10 BUSINESS DAYS FOR MY MONEY TO BE PAID BACK

I PURCHASED AND PAID FOR A COUCH ONLINE ON THE 27TH NOVEMBER, A WEEK LATER I RECEIVE AN EMAIL TO SAY THAT MY ORDER HAS BEEN CANCELLED AS THEY UNABLE TO SOURCE THE COUCH. I EMAILED TO ENQUIRE WHEN I CAN EXPECT MY MONEY TO BE REFUNDED, NO REPLY. I THEN PHONE THE CALL CENTRE ONLY TO BE TOLD I WOULD NEED TO WAIT 10 BUSINESS DAYS TO HAVE MY MONEY REFUNDED. WHY DID YOUR SYSTEM ALLOW ME TO PURCHASE AN ITEM YOU DIDN'T HAVE IN STOCK! HURRY UP AND PAY MY MONEY BACK!
