Poor online service

I am utterly disappointed at woolworths online shopping ( Dash woolworths). I have not received my refund of R999 grocery shopping. It has been over 1 month now. I have called online services, sent my documents but still no refund. The delivery guy just went off from my gate with my groceries. Delivery was from Musgrave woolworths Dash. Called the customer line same time but was told I will be refunded 7-14 days working days. Until now I have not received my money after consulting many times via emails and phone calls order no:***.
