Bad customer service from MultiChoice

I app**** for the price lock in January 2018 and application was approved. I called your call centre a couple of times to find out when will I get my xplora. After I made a couple of calls and I could see that your agents aren't able to assist me I decided to leave application as I was just waisting time my air time calling MultiChoice. Last week I called to update my details and I was asked if I am still interested I told the lady my whole story and she said she will get someone to call me. An agent called me and I had to again start afresh to apply for an explora and the application was approved. Immediately got an SMS telling me that my Explora has been dispatched and they gave me the reference number. Yesterday I got an SMS from courier company telling me to call them so that I can make an appointment so that they can deliver my Explora. This morning I called them with my reference number and now I am told the reference number does not belong to me and that the parcel has already been signed for by someone else. I really don't know why is happening at MultiChoice ......????????? This morning I spent already 20 minutes doing the following with your call centre using my own minutes
