DSTV disconnects for 3rd time in 11 days even though payment is up to date

We have been DSTV subscribers since I can remember, we have never missed a payment. We signed up for the Black Friday deal where you get an Explora decoder, including everything for R749 pm for 12 months. We also took a second Explora decoder which will cost R49 pm for 24 months. All was installed and we then changed our debit order date from the 7th to the 30th of the month. We stopped our PVR subscription and everything was ready to go. We paid our new installment on the 30th of November 2018 but our services were disconnected for non payment on the 10th, the 17th of December and again today - 3 disconnections in 11 days for non payment when our account are fully paid!!!! When I phoned them the first 2 times, they said we were loaded on the normal price lock package and this was apparently escalated and will be sorted out. Well, I don't think it was because we are disconnected AGAIN! It is now 5am and I will definitely be phoning them again this morning and I will not be as understanding as the first two times! We pay through our necks just to be able to watch some TV but incompetence on their side now makes me wish we never signed up with them to begin with!
