no delivery since March

I was approved for a DSTV Explora deal (R449) in March. To date, no delivery, no nothing, I contacted almost every communication platform from multi choice and i am still not getting any assistance. On the system it shows a certain installer has my decoder for installation but when i contact the installer, he has no decoder for me and this is what multi-choice has been doing for years and it is giving them a bad name since they send us SMS's stating that they on their way to install while they have no decoder delivered to them or me. I was told that the system shows it is on route and to contact the courier. I then contacted the call center agent and all they said they could do was escalate the issue. I was asked my parcel/tracking number and I have never received one. It was obviously a blatant lie on the part of the first agent as she told me my Explora was with the courier and it was not. I have been debited the R99 once off fee already which means you have entered into a contractual agreement to deliver the Explora in the said 7 to 14 days. You have not and need to rectify this situation immediately
