No express at Builders Express

Experienced the worst service ever at Builders Express Hypermarket in Durban North. I went in to get a litre of paint which had to be custom mixed. I waited patiently while the another customer was having some paint mixed, manually might I add. There was just one person serving so i had to wait until this customer had been served. Having waited a solid 30 minutes, it eventually came to my turn to be served. I hand over the colour I was looking for, only to be told by thr assistant that their colour mixing system was offline or not working. He tinkered with it for a bit, but without success. Then I am told that this is happens often, as if to excuse the fact that I couldnt be served. What incredibly lousy service from Builders, and it won't come as a surprise if other customers have experienced same. For one, the paint section is clearly in need of more staff to assist customers. The paint mixer appears to be an ongoing problem, so why isn't is sent for repairs. The assistant on duty could have informed me sooner of the system issues and saved me having to wait half an hour for nothing. Customer service is clearly not priority for Builders, Hypermarket.
