Useless Woolworths

I'm really ****ed right now.

I ordered food and clothing from Woolworths online on the 4/4/2018 and it was for delivery on 10/4. On Monday they put my order on hold after phoning me at 8am to clarify my order. At 4pm I phoned to ask where my order was and I was sent from pilar to post. At 5pm they then offered to have my order delivered on Tuesday 11/4. I then refused and requested a refund and went on my way to shop for the groceries I never received???? Tuesday morning I was phoned to say the information for my refund is incomplete- my card number wasn't complete AFTER the consultant on Monday said the refund has been authorized. LIES!! Now, its almost 4pm on Thursday and they have NOT refunded me. They also say that they had reserved part of my funds and they are not responsible for returning it back to my account. What nonsense is this? I paid R1700 plus they have only "refunded" R800. I've also wasted time, airtime and petrol because of their incompetence!
