Locked post box

<p>I renewed my post box in January at the branch. A few months ago my post box was locked and I enquired at the branch and they looked it up and said it was a mistake and opened it again. Now once again it has been locked and when I went into the branch they say it hasn't been paid!!! How does your system</p> <p>work? It just changes all by itself and now I have lost my proof of payment and I need to pay R400 for</p> <p>nothing!!!</p>
