Pathetic customer service!!!

I called dstv and had the horrible experience of speaking to Noxolo. I called as the service is inactive. She informed me of an amount to pay additional to my monthly subscription price lock R549.00. I asked her where the additional amount comes from she said it is prorata and charges for the decoder when the package was downgraded. I told her the price lock is including the decoder so i paid the R549 that month it is including the decoder. How can i be charged twice for a decoder in the same month. She just continues to threaten me if i dont pay my account will say blocked. I asked to speak to manager she doesn't even take down my number and wen i asked her to take down my number she doesnt respond so i ended the call and went to check the statements and found i was charged for both packages in the 2 months yet i didnt change packages. My advice is don NOT take price lock DSTV robs people of their hard earned money. They dont care about customer service only money!! Noxolo u are in the wrong industry with poor training on how to be helpful!!
