Four days and still no changing decoder owner

Four days ago, I went to Multichoice Agency I Alberton, what a shocker, staff watching cartoons, volume so loud you cannot communicate with them, I have emailed to Randburg Head Office, or so called all the necessary documents to change my sisters decoder into my name in order to add extra view on my premium package for her,,,,affidavits signed the commissioner of oath....whatever they requested....not one word from Head a Office...four days and nothing has been done? Something that should take five minutes.....are the staff doing their jobs or just ignoring all requests and paper work? What actually gets done in those offices.....it is beyond ridiculous.....I think the service is a disgrace.....my ID ***....and one cannot communicate with the correct department as they don't take calls......
