Builders does not care about it's customers

Ordered and paid online on Monday, received an SMS that evening that my order would be delivered on Tuesday between 8am and 6pm. No one arrived. Called Customer Service on Wednesday only for them to tell me that delivery would be on Saturday! Asked to change the order to a collection and to get a refund of the delivery fee and the agent said she would have to consult with the store (Walker Drive, Port Elizabeth). I asked her to transfer me to the store and after waiting for some time she advised that no one was answering their phone at the store - can't say I was very surprised as it was becoming clear that Customer Service is not a priority for Builders. I guess I will have to drive to store to get a semblance of an answer.
