Ridiculous online order delivery service

Ordered a fridge online on 24/11/2017, paid delivery of R70 for 3-5 working days, on 06/12/2017 after waiting 8 working days I called the branch my fridge is supposed to come from, they promised that my fridge would be sent out for delivery on 07/12/2017, on 07/12/2017 I called the branch to confirm if my order had gone out and I was told that the order would go out that day or the next day 08/12/2017. Order was not received. On 12/12/2017 I called again to find out where my order was I was again promised that my order would be out for delivery the next day 13/12/2017, which was just another lie as today 16 working days after order was placed my order has still not been sent out for delivery. Today I have been told they never had stock of the fridge and they have now received the stock and it will be going out for delivery this afternoon. A huge retail company should not have such terrible service.
