Dont buy appliances from Pick'n Pay Northgate if you want service

I bought an upright freezer from Pick 'n Pay Northgate 2 weekends ago. When we were there, It took me 30 minutes to find someone to help us!!!! We were then helped by Lucas who really didn't know anything about the products and had to keep going to find out when we asked questions...we bought the last freezer on the floor to be delivered today 10/12/2018 first thing in the morning (like 9.30am) as promised by the sales person Lucas. I arranged for someone to stay home from work this morning to wait for the delivery before going to work..we have been trying all morning to get an answer on when we can expect delivery and have just been told at 11am that it will be sometime after the delivery truck has been to Greenstone, Edenvale today!? what!? No rough estimate, nothing!? Now the person at home who is late for work will probably miss the entire day of work waiting for this truck and lose a days pay..how do I get that back?? The calls made to the store have been something else entirely!! put through to every single department where they are all shouting to eachother in another language then placing me on hold only to be put through to another person who also has no idea what i'm talking about is beyond frustrating (very professional guys - NOT)..then to be told that "we will call you back with answers" is a JOKE because we are still waiting!! Now I spent R2999 on this freezer which is allot of money for a single mom and I get this kind of service!! I want to know how I will be refunded for this day's pay that has been lost on my side?
