poor service, they don't don't honor their promises on they proposed date of delivery and time

i am so disappointed by the level of service i received from Builders warehouse Erasmus Park, i bought online they were supposed to deliver on the 28th but they never did and never bothered to communicate with me, i contacted the branch on the 29th at 9h00 am and they promised that the manager will deliver with his own car and that he is on his/her way to my address that was around 9h00 and i gave instructions that they need to deliver by 14h30 but they never did. I had to call them again at 14h25 to check how far is the driver and i was informed that he is on his way, i requested his contacts and i called him he told me that he wasn't told that my parcel is a priority and also he had a puncher from 10h00 till 14h30 which i know is a lie. This is the second time i receive this bad service and i have realized their drivers are not trained as they can even insult us the clients and they show us that they don't care about our service. I will never recommend builders warehouse as it has failed me and they don't even follow up to check if your issues are resolved you end up calling them without any assistance as if you didn't pay for what you bought. Their dispatch department is very poor and unprofessional as we speak is 17H37 and my order is not yet delivered. I regret doing business with them
