DSTV - billing disaster

Been billed twice. Call center can't help, they not know. Phone accounts -they don't know, I must call Pricelock -they don't know-phone call center-they don't know. Try FB - no response apart from give us all your details. Try what'sup - you have the self service option. What a nightmare. This is now month two of billing problems. Seems they are not at all interested in sorting this out.
