Courier company that do not do delivery services

They never deliver the package. Every few days, there is a new message that tries to deliver, but they lie; they never tried, someone is just updating and sitting somewhere, and doesn't do any deliveries. You can't even get hold of anybody on the phone; they're always busy, and even then, they just drop the call. Now they notify me that the package was sent back to temu because they can't get hold of me. If Temu is using this company again, I also will not buy from temu while they use this courier. If I see it is with this courier, I'll request a refund for the product and try again later until they use somebody else. It's a typical South African attitude: we get paid, so why deliver any service
