No delivery when confirmed via sms

Ordered a fridge online on black Friday. Delivery was scheduled for Friday 3 December. Received a sms that it will be delivered between 2 and 3. By 4 I phoned their customer service number and no one answered, left a message and no one phoned back. Saturday 4 December 17h20 the driver phones me and says he is at my gate and I wasn't home as no one informed me that it will be delivered on Saturday. Told the deiver to back Sunday and was told they don't work Sundays it will be delivered on Monday. Now I want to know what must I tell the company I work for? Sorry I can't be on the road today to see clients because Pick n Pay will maybe deliver my fridge today? Why have a customer service number if no one assists a client and there is also no way of tracking a delivery.

Your company can learn a thing or 2 from Game who delivered a parcel on a Sunday at 18h00 2 days after placing and order and after receiving messages with a drivers number so he could be contacted to get a time he will be at your door, and this after the site said delivery within 3 to 10 working days.

Tomorrow morning I am on the road as that is my job and I would appreciate it if my fridge will be delivered between 14h30 and 18h00 or refund me so I can support a retailer that wants business.
