NON SERVICE DELIVERY

I think the SA Post Offices must all close! Their service is non existing. I wish I could give them a 0 rating because they do not even diserve 1 star! A week ago I got a notification in my mailbox that there is a Registered letter for me. The notification was dated 22 Feb 2022. I went to the Menlyn Post Office for the Letter where I was told, that the letter is not with them any more. When I told them that I only received it on the day I wanted to claim it; I was told it is not their proble if deliveries do not do their work! ( Today I received another notification for the same letter dated 03 May 2022.) !!!?
