Poor Service

I would like to warn everyone of the poorest customer service from Rustenburg Builders warehouse, i purchased building material on the 24 February 2022, i was promised that my delivery would happen within 3-5 working days with a request that the store contact me first before delivery, On the 28th around 8:30 i was called by the store to notify me of my delivery i rushed from work back home only to be told i would only receive part of my order the rest was going to be delivered once their driver came back from Rietspruit, meaning another load would be delivered later that day, i could not wait the whole day for them i then made an arrangement for 3pm in the afternoon, later that day i received another order still with outstanding items , the drivers then promised that since it was already their knock off time they would deliver first thing in the morning, i then arranged with the constructors to come and start off work since i knew that all my outstanding would be delivered first thing in the morning not knowing that i was wrong, on the 01 of March i then decided to call the store to follow up on my outstanding delivery i interacted with an employee by the name of Jimmy, who lacks customer service to the core, he then told me that the cashiers should have explained the delivery process as its not his problem that i did not receive my order on the scheduled time, i then explained to him that I did keep to my schedule, he further told me that he doesn't care that i pay my constructors per hour and I'm losing money for their miscommunication, he further said i can escalate he doesn't care. i kept calling their store their phones are unanswered i wonder how does Massmart run their business with such *********** employees?
