Delayed delivery. Absolutely rude customer service!

We placed an order online on Tuesday, 2019/08/20. Payment was made and the order confirmed that delivery would take place in 1 working day. On 2019/08/22, we called the customer service line to ask about the order. They said they would find out and get back to us, but they never did. We then called the Alberton branch, but they kept giving us the run-around. We then called head office who put us in touch with the branch, only for the branch manager to completely disregard our query and we were told he had left for the day at 16h15 in the afternoon. Today, the call centre called back and asked if we received our order. Told them that we hadn't. They called back and put us in touch with Themba from the branch. All he had was excuses and didn't have an answer about where the order was. I told him the site mentioned that stock was available at the branch (per the site and email confirmation). He stated that he didn't know why but they still had to order our goods. When I asked when he would know and why would he phone me without answers and no real information, he HUNG UP on me! Disgusting representation for Builders Warehouse. Terrible service and a total disregard for customers who only want to know what is going on with an order that should have been delivered 3 days ago! This was not a small purchase. We will take our business elsewhere next time.
