BAD SERVICE!!!!

I BOUGHT A SOUND BAR FROM THIS STORE WHICH I WAS TOLD WILL BE AVAILABLE FOR COLLECTION AFTER 3 DAYS. 4 DAYS LATER I'M CALLED AND TOLD I HAVE TO COLLECT THE ITEM AT THEIR WAREHOUSE IN JET PARK OR PAY R150 TO A CERTAIN GUY WHO CAN COLLECT IT ON MY BEHALF. ALL THIS IS COMMUNICATED AFTER I'VE MADE PAYMENTS, I FEEL THIS TYPE OF SERVICE IS DUBIOUS AND MISLEADING THEY SHOULD HAVE COMMUNICATED ALL THIS BEFORE I COULD FINALIZE PAYMENT. I HAVE BEEN TRYING TO CONTACT THE STORE FOR OVER THE WEEK SOMETIMES THEY ANSWER THE PHONE AND PUT IT ASIDE OR IT JUST RINGS UNATTENDED. AT THIS STAGE I JUST WANT MY MONEY BACK. THANK YOU
