Disgusting Service - DSTV Price lock.

I ordered a Dstv Premium decoder through the Dstv Price lock sms, the decoder was ordered on the 22nd of June and dispatched on the 28th of June from the warehouse . The decoder was only delivered to me on 08 July 2021. The incorrect decoder was delivered to me. The docder that was supposed to be delivered is a Dstv ultra decoder but a Dstv explora 3A was delivered. I even confirmed on my Dstv login site to see that the seriel number on my profile was different from the decoder that was delivered. I then sent a message to the DSTV 24x7 message bot and was given a reference number Ref ***0. I was the contacted by a consultant from Dstv price lock department who promised that they will track my decoder and get an installer to my house to have the new decoder installed as per our contractual conversation. Till today 17 July 2021 ther has not been any contact. I again went to the Dstv bot and messaged them to say that the matter has still not been resolved only to be told that it is closed on their side and he is going to re-escalate the matter. REALLY. This is unacceptable from a company as huge as Multichoice. I have been a Dstv client since 1999 and this is they type of service i get... I want this matter resolved urgently.
