Builders *******

You go to builders to buy paint for a caravan, the advice the so called assistant gives us that you need his particular one, so you buy the product. Low and behold it's the wrong one. The person doing the repair says you need a bitumen based paint. I take the paint back to be told that the system has deleted sales from my ACC after 3 months , a the sale doesn't show on their system. Now I sit with this ******* that I can't use. People don't buy from them unless you know exactly what you want ,as they don't take stuff back unless you have all the facts as their sales people have no clue ,they only want to sell you their ****
