Defy not helping serivice sucks!!! No e-mail address for them!

I am very sorry to say this but the service sucks. I bought a new double door F740 fridge on the 2nd May. It worked for 8 day, had a battle to get service department to get s tech. To come and solve the problem. They was there for 5 minute, brand new fridge gas pipe broken fixed it and put gas in. They were the for 5 minutes. Fridge started to work but refrigerator side stayed warm. On the 18th it stopped working. Ot is the 26th today still not sorted. I lots everything in fridge and freezer twice now. Now i was told Venessa Kotze will contact me. I spoke with a Jonathan, Phindile, Salome, Sibiso, Luvono, Lefono. The last person Buso. I sm very upset. The should have swopped it imediatly for another double door in my view. Call centre no. ***
