DSTV HOLDS CLIENTS TO RANSOM

I called on Friday and requested to downgrade on my package. My package expires on the 27th. So the lady then told me if she does it on Friday, the package will immediately change and we won't have those channels in the evening. I was told to call back. I called back today as I couldn't call yesterday and I was told no, I need to pay the full fee and it will only be scheduled at the end of Feb. I said no DSTV cant have it both ways. I called to downscale on Friday and she gave me the incorrect info. Why should I be held to ransom
