Builders warehouse

Hi, I went to the builder warehouse Vanderbijil park store to purchase boards for wardrobes the cost was 2675.00. I was told I can collect in two days. But then I receive a call from a man , telling me that they made a mistake the boards that I want are the last in stock and someone purchased them. I should take the whiteboards as a replacement with the same price.on 11/10/2021 the store tells me who did I speak to because I will have to add money on the boards available. I am so disappointed with the service what a waste of my time and energy.People are so dishonest to a point where we are pushed not to visit the store.I am speechless , the store doesn't care about the efforts that customers make to their store and this is emotionally draining.
