Lousy service

We have been supporting Universal Paints Randpark Ridge for years and their service was good. A few months ago we bought a few tins of paint, used all one tine was left which we sealed. We open it now and it's off. Our builder says paint should not go off in such a short time. We contact the branch and they blame us for not sealing the tin, so we say we are not happy with that response. The person says he will get the store manager to phone us - we are still waiting. So, in trying to save a bit of money they lost a long-term client - brilliant marketing startegy! Neither our builder, nor ourselves will go back. Hello Chamberlains and Builders Warehouse where we have no hassles.
