Still waiting for dematerialising of shares

Sent original documents with correctly completed relevant documentation via couriered mail (5/3/2015). I contacted their call centre on almost a weekly basis. They acknowledged receipt of the documents and I have been given a waiting period of +- 3 weeks.<br> <br> My enquiries are still ongoing, receiving the same response, i.e. that it is being prioritized and being processed. <br> <br> I have spoken on different occasions to the following persons at the call centre : Keeghan, Chane, Lolita, Nkuli, Mamelo, Sandra (from my local Old Mutual office where I went in desperation), and once again Keeghan.<br> <br> To date, only Chane called back to confirm that the paperwork is in order, but that it seems to take very long. How far do I need to go to get my shares sold?
