Poor customer Service

I bought materials on the 10th August 2024, delivery date was 13 August, I went on the 15 to check what was the delay I could see that they forgot about my order. Today is the 16th August no delivery still. The builder is waiting and it's costing me money and delays to my project. What kind of customer service is this? Cashbuild went and closed the best one in Lenasia, I don't understand the useless Southgate one should be the one that was closed. Even on the day I went to buy there was a lady that was complaining about the same thing. One last thing the people working there have no customer etiquette none what so ever cashbuild must invest in its workers and take them for customer service training.
