Bad service from Walmart East Rand Mall

I purchased a washing machine in-store on the 13th March 2026 at Walmart East Rand Mall. I was told they don't stock in-store and they will order from DC and call me when my order is read. I called the delivery guy on Saturday morning and told him I'm not home after receiving the SMS, we arranged for Monday, after receiving an SMS today I called him, Mandla and we agreed that 3pm my delivery will be made, I got a missed call at 13:54 which I called Mandla back as I did not recognise the number that called me, he said he'd check who called and get back to me, I called him again at 16:20 and he said he's going to check and get back to me, I got a call from a rude man asking me why wasn't I answering my call as he was at my gate at 2pm, I asked him who did he arrange that with and who is he, he screamed at me and hung up, I called Mandla to tell him his guys are rude but I want my delivery today he said he'd call the driver but promised to deliver tomorrow morning, I told him I want my parcel today or I'm calling the store to cancel this order. Bad on communication and updates. I don't understand why the store did not call me to check if I'm available before dispatching my order or make arrangements or update me on my order
