Makro Carnival, poor customer service!

The service at Makro Carnival is poor. I bought a Defy fridge in January and it was delivered with defects. I called they picked up and delivered another one with the similar problem. It's been more than 2 weeks since they collected the fridge, I don't have a fridge and the worst thing is that they don't even bother to update me. When I call I am being sent from pillar to post! Worst service ever!
