The lady who assisted me, Linha, said that I had until February to pay for the renewal and that I should wait for the renewal slip to come in the mail before paying. I obliged and left. <br> <br> Weeks has since passed and no slip has come in the mail. I returned to the post office on 5 February 2015 to pay the renewal fee. I was served by the same lady who now tells me that I am overdue on the renewal account and need to pay the penalty.

When I requested to speak to the manager, she advised me that the manager was busy doing admin and could not speak to me. When I requested the managers name, Linah, refused to tell me. <br> <br> I had no option but to pay the penalty as well as the renewal fee.
