The SA Post Office fails to deliver a service through boxes

I have rented the post box for over 25 years. The annual rental of about R495 is not worth it. Access to the box has been nonexistent since the beginning of 2020. There is no communication about this lack of access. i will have to suspend my annual subscription and bear the consequences such as trapped mails items and having to update my details on my existing contracts. It is bad and unfortunate
