Dstv was cut off for no reason

We recently upgraded to the Dstv Explora, and added our older decoder with our service, Multichoice told us that we had to pay just over R300 end of the month, and without any notice our service was cut off because of the R300 before our usually pay date so how can one person say it is okay and then it is cutted off it is not fair, and the people at Customers Service is very rude and not helpful at all, so we made a payment again but they refuse to switch it back on until the money reflects on their side which I understand but why did we not get a warning in the first place and why are customers service to freakin rude and just never wants to help they just tell you their system is off phone back later and drop the phone, but we should pay dstv makes me wonder if it is even worth to have dstv at all.
