Poor service and product from Bradlows and Defy

We bought a SBS F740 double door Eco Defy refrigerator at Bradlows Thabazimbi Limpopo around October 2017. At the end of November 2018 we reported a fault whereby the door on the freezer compartment was not closing. The freezer was not working as a result. The store logged the fault with Defy. They came to inspect and said they must change the door seal. The seal was subsequently changed on 23 Jan 2019. Four days later the freezer compartment stopped working. I reported again at store and Defy change the freezer fan motor on 04 Feb 2019. On the 10 March 2019 the freezer compartment stopped working again, flashing an error on the display. The issue was reported on 11 March 2019 and two days later we haven’t received any response. The said thing is that both the store and Defy say there’s nothing they can do. I must just keep on reporting when there’s a fault with the s**** they have sold us.
