Cadac Dismal / Poor Customer Service

After contacting CADAC about an almost new defective 9kg bottleI was told to drop of the bottle by a receptionist called Natasha. 2 months later and calling them many times about when this bottle will be ready I am told indefinitely. We are half way through winter and CADAC South Africa cannot tell me when this bottle will be Fixed. Surely this isn't good customer service for a big brand like this.
