Bad Customer Service

I bought an item at Woolworths online last month, 2 days later i called them and cancelled the item because i realised that it was not exactly what i was looking for. They cancelled the order and said that they would refund the amount back to my store card that i used to make the purchase. Up until today no refund from Woolworths. I have called them and spoke to 4 different people who have promised that they would process the refund back to my account.

I am tired of chasing after Woolworths wasting my airtime every week calling them to do their job properly. My order number was o***.
