Where is my mail and key deposit

Due to relocating I cancelled my Post box on 7th April 2018 and returned the keys to the branch. I then completed the paperwork for my mail to be redirected for 3 months and was charged R195.00 for the service. I then proceeded to complete the forms to have my key deposit refunded. It is now 1st June 2018 and no mail has been received at the forwarding address and nothing has been heard regarding the deposit. The Post Office saying that they always deliver is a joke. Which ******* bin do they deliver to as maybe my mail is there. I have been charged good money for a service that they do not carry out. I recommend that anyone relocating should leave the keys with a friend to redirect the mail and then just throw away the keys at the end of the year.
