Terrible customer service when ordering online groceries

I was supposed to receive my online grocery delivery order on Wednesday, Dec 23. At last minute, they called to reschedule for Thursday, Dec 24 (fine, at least it's still before Christmas dinner which was what the food was for!). On the 24th, I waited all day at home as they said it was "Out for Delivery", but I never received the order. That evening around 6pm a representative called saying the food had been returned to their store by the driver, but they didn't know why. They asked whether I'd like the delivery instead on the 28th to which I declined and asked for a refund. They indicated they would cancel and cancel the charge. Two days later, today I see the amount has posted to my credit card. It took almost two weeks of sending 3 emails and calling the call center 4 times. I was always promised they would get back in touch, but they only followed through after about two weeks. Finally in mid-January the charge was reversed from my card. That's almost 3 weeks after more than R1000 was taken out for food never received. I will NOT be testing out Woolies' online delivery service EVER again. I stick with Checkers Sixty60 which always arrives within an hour (although not always with everything ordered), but still a much better service. Shame as Woolies in-person is such a strong product.
