Poor customer service and feedback

I've been waiting for a delivery that was due to come from Temu on or before 5th June. I could see that it had arrived in the country in mid May and was set for delivery on the 31 May. Then, when tracking, I noticed it wasn't the usual company I'd had in the past, but 'The Courier Guy' who had been assigned to deliver. I watched the tracker over the week and could see early in the week that the parcel was here at the Durban Hub for The Courier Guy. Due date, at the latest was still set for Friday 5 June. I phoned quite late on Thursday afternoon and spoke to a consultant who told me that the order would indeed arrive on Friday. Cool, no worries there. Waited all day on Friday for delivery, but eventually called the call centre again at around 4:20pm just to be sure. Spoke to a great gentleman in Joburg who said the parcel hadn't even been assigned a driver. The consultant was going to escalate the matter and then someone would phone or email me with an update. He also said the parcel might arrive today (Saturday 6th), but that I'd be contacted with an update. Today has now come and gone- still no delivery and still no one contacting me. So I tried the whatsapp number. At 13:44 the app told me I was being transferred to a consultant who would contact me. Needless to say, it is now 20:30 and no one has contacted me or answered my query. I had no control over the fact that The Courier Guy was somehow selected by Temu to deliver on their behalf, but I can assure you that I certainly won't be choosing them when it's time for me to Courier items. I can handle late deliveries, but I can't handle sheer lack of service and feedback from a company that supposedly prides themselves on both.
