I am NOT getting any ASSISTANCE FROM DSTV!!!!!!!!!

One of the reasons why I cancelled my subscription with dstv is their less than worst customer service and the lies that their agents will give you, I called way back to cancel my extra view and only keep one decoder active under their R110 package, the lady I spoke to promised me that they will definitely assist and cancel, calls are recorded for crying out loud, then I checked my balance again, and I still had the extra view amount charged on my account, I then called and spoke to keighleb who gave me a reference no:***0/I100 and made a promise to me that, the extra few amount would be reversed in 24hrs, guess what the amount is still there a week later, then I called again and had to repeat my frustration again to Devan who gave me a reference no: *** and again a false promise was made by him that someone from Management would call me to resolve my issue, where I'm paying for something I asked to cancel 2 months ago, I cannot lie, the service offered my this Big company is shocking to say the least, and I'm sure even this review will not even get to a person that will assist, it's no wonder why people are cancelling to go to Netflix, how on earth can I sit with such a small issue for so long yet they have no real competitor, who do we then speak to if the people they in their forefront makes false promises, dont resolve customer's issues, dont get back to their clients
