Poor and rude service

I spent about R1000 at the Cornwall Hardware on the corner of Piering and Boeing Street which included a 5 litre tin of colour mixed paint and specifically checked if they were open on Sunday in case I needed more paint. When I went there on Sunday to buy more paint to finish the wall I had started, they had not recorded the paint code on the tin, which is the norm. Staff simply refused to assist and claimed they are only human. When I explained I needed to finish the wall that day, they claimed it was not their problem. The manager provided no assistance and refused to get the owner to contact me. I left my number requesting a call from the owner - 4 days later and still nothing.<br> Found out later that one of the other tins of paint I bought for R359 sells for R279 down the road - exactly the same paint.
