Bad postal services

I ordered a small parcel from eBay on the 25.09.2025 and as per seller the parcel will arrive in 3 weeks, and if it does not arrive then as per eBay policy I get a refund. I waited the 3 weeks and seller said to give it another week so I said okay. After about 5 weeks I told the seller parcel has not arrived and they tracked the dates and arrived on time in South Africa but still refunded me. I received the parcel end of January, the parcel was delivered through the South African postal services into my home address post box. This is not the first time I placed an order and the post office never sent the parcel to date and it just vanished as it was tracked by seller until arrival in South Africa, this happened a few years ago. But good to know for future people using the post office fort postal services. I will not use the post office again for delivery or sending, I will rather pay extra for courier service.
