Registration issues

<p>I registered on 17.07.2016 for INV2601 (final module) and paid on 19.07.2016 but UNISA has not taken that registration into account. I sent an email to their Registration department on 25.07.2016 but still no response. I am very frustrated as this is one of my 2 very last modules. all their contact numbers listed on their site do not work. </p>
