Bad services from Woolworths online

Woolworths still hasn't refunded my money I canelked my order on the 27th of May 2020, was advised that I'd get my refund between 3 to 5 working days. Called last week in the 3rd they couldn't assist, called again in the 5th still haven't received my money back... Called again today had to hold on for more than 20mins only to receive the news that my refund wasn't processed...
