Terrible service from Sibusiso

I received terrible service from Sibusiso Mahlangu at Medirite montana early in the morning, firstly he ignored me while I was on the que, I then decided to approach him,greeted him but he still continued with packing some paperwork.When I asked him if he was open for assisting customers on his till he rudely asked me "how can I help you",very shocking how people don't value customers.I am just disappointed in the kind of service we receive as clients
