Why the change 'Safia'?

The first good piece of advice I received when I first landed in Sudan was to drink plenty of water. It is said that one who drinks the Nile water keeps visiting this dry hot country. Drinking straight from the tap may not be a good idea.Bottled water or ‘Mineral Water’ is a better option. There are many brands from different companies. The brand with high equity is DAL group’s ‘Safia’. I have always preferred it. But once you are loyal to a brand and one fine morning you find that the labeling design and colour has changed and there is no communication from the company as to why it has changed, it is difficult to gulp down the water. DAL group is known for their Public Relations or communication with their consumers. We need to know why the change? Apparently there are no changes in composition.
