Unprofessional and inconvenient

My Shein order was shipped to SA into BUFFALO warehouse of which I paid for courier and I was given a tracking code to track how far my parcels were. On the 18th October 2022 the status said "Dispatching" which meant parcels are on my way to me, Later that day I went back to track the parcel, the status was "Address reachable, TEL undialable", curious, I called the next morning 19th October 2022 to ask what this meant, the consultant said it means I wasn't reachable on the phone the courier was there, which was a plain lie because I never received or missed any calls. But they assured me that I will get my parcel that day (19/10/2022) but when I track it, the status is still the same as the day before, I still did not get my parcel. Today 20/10/22 I checked again the status said "Trying to deliver again", at 3pm I checked my status again and says "return: misoperation" .I called AGAIN, the consultant said the driver probably decided they are not coming to Vereeniging. So to me it means delivery time depends on the whether it inconveniences the driver or not and that's just OKAY. I emailed this to the email address that's on they're emails messages, I sent Whatsapp texts on their Whatsapp number, I haven't received any reply. It's nonsense! Today's consultant said I can arrange collection but I won't get my money back. So I'm supposed to spend money to go collect on top of the airtime I'm spending calling them every day! I have an important occasion on Saturday, But all that relies on how their drivers feel.
