Multichoice Dstv Explore upgrade

Hi. I went into Multichoice on Thursday 7 March to have my dual view decoder fixed. I was given the opportunity to upgrade to the new Explora for R5 extra per month. The assistant advised that they will come to my home and do the installation on my behalf. This was scheduled for Friday 8 March between 1pm and 2pm. At no stage did I receive a reference number (which was supposed to be sent to me via sms) No one arrived for the installation. I phoned Multichoice on friday. They advised me that the installers couldn't get hold of me because the assistant incorrectly entered my phone number into the system. They told me over the phone that the number is now updated. The call assistant advised that the installers will call me on Monday 11 March to arrange for a new installation date. It is now 13 March with no call, or reference number sent to me confirming the upgrade. The worst part is that I told the assistant on Thursday 7 March that this is what will happen, and that I will either sit on the phone for 2 hours to sort this out or send a message on HelloPeter for this to be sorted out. So here are we now.
