Namibian Breweries

I have twice written to Nambian Breweries over the last 3 weeks trying to ascertain why their Tafel Lager 500ml cans are unavailable in Durban. There has been no reply from them which I find very frustrating and dissappointing. Having visited every major retailer / outlet and I have not been able to purchase what is a very good product. It would appear that they have no interest in keeping their Consumers satisfied.
