Milk never in stock

I would like to complain about clicks in Bizana walk, everytime I go there and buy Milk (Novalac IT2) there is never stock, this is the third time this is happening, now I have to resort to going to Port Edward which is so many KM's away and I take public transport such an inconvenience seriously. They need to increase stock in this milk as clearly there is a demand for it. How do u order 4 only at a time. Honestly this is bad.
