Pathetic service

We bought a defy 425 combo fridge freezer on the 04/12/2018. Paid cash in full as well as the deliver charges. The salesperson explained there is a back log due to black Friday so wee arranged the delivery for the 14th after 12:00 in the afternoon. I visited the Menlyn shopping centre branch on the 13th of December to confirm the delivery for the next day. The sales lady confirmed. On the 14th spoke again to Leonard (sales manager) and he guaranteed our delivery. And the delivery came. We have a new fridge. All is well. No, it's not, and here is where all the wheels came off. Our new fridges water dispenser doe not work. So on the 15th I took a drive back to Menlyn to sort this out. I was told that I can only be helped the 17th due to the weekend and ounkuc holiday by both the sales lady as well as Leonard. This was already unacceptable. The Leonard says he can loan a truck and pick up a fridge from another branch and delivery it on the 15th, he cannot promise time but he promises it will be on th 15th. But no delivery. The sales lady phones me at around 17:00 and apologizes for herself and on behalf of Leonard, who made the empty promise), and will only help on Tuesday the 47th. So to sum up. We paid for a fridge on the 4th, a broken one gets delivered the 14th, we are promised a new one on tb 15th but will hopefully get it by the 17th. This is pathetic after sale service. Why aren't there back up plans and why are empty promises made. This will be the last time I buy from game.
