Annoyed Client

I app**** for DSTV Explora 3 Price Lock ,on Monday the 25th of February 2019 I received a call from the courier guys confirming my address so that they can deliver my decoder ,fair enough I asked them that are coming to deliver it today then they said yes ,Monday ,Tuesday I hear nothing from the delivery guys ,then Wednesday morning I contact them the delivery guys ,they advise me that they got hijacked ,then I said to them don't you guys have a decency to contact me and tell me that you wont be coming rather than letting me wait for you while I was supposed to be at work. Multichoice is very big company to associate themselves with immature low standard courier companies to service their clients ,am so ****ed and annoyed the way Multichoice is treating their client,Is it because you guys don't have competitors in the market ?I have called your call center no one can assist saying that they don't have details of the courier company, am taking this complain to the media am sure am not the first and the last person to complain about the way you treat your clients.
