Shocking Customer service from store to HQ

we bought a fridge from the Greenacres store in Dec 2015, it was faulty and we reported it a week or two later. We were promised a new fridge in Feb. It is now March and they still cant tell us when the fridge will be replaced. They even told us to bring in the faulty fridge ( how i am not sure). Called HQ and after 7 dropped calls from them, i get transferred from Pillar to post, even transferred while i am speaking the person. So it would appear the stores get there customer service passion from HQ. Appalling service but very quick to make the sale
