Dstv not listening

There are times when you are not assisted and then times when it becomes too much for you. I have had terrible customer engagements with DSTV in the last two months. Today I was highly aggravated cos a dstv agent changed my debit order date without my permission.I.mereltyasked what the amount owing will be but did not give permission to do so. I had to go back onto their chat site to gave it changed back to the correct date again. I highly irate with the incompetence and do not wish anyone else go through the highly bad service
