Disappointed in the service at the post office

I am disappointed in the main depot post service in Jo-burg. I have been trying to track a registered letter since the 1 July which has not even been scanned into the system yet! every time i call its the same result which no one is able to elaborate on. No one responds back to you on e-mail and getting through on the call center is just as much of a challenge due to their 'high volume' of calls, presumably by other customers also wanting to search or complain about the same; namely packages/ letters not received or delayed. Very disappointing.
