Good afternoon I have complaint for Dstv, my monthly subscription is R514

Good afternoon I have complaint for Dstv, my monthly subscription is R514.00 pm.End of June their App showed that my balance is R-25..then mid july the App showed that my payment due 01/08 is R489.00 meaning that R25+R489=R514 i paid R489 around the 21/08 to cover my payment due for 01/08 then suddenly there after the App shows that R539.00 is due 01/08 i wrote them an email to query this their agent called me, she asked if i have won any Dstv rewards i said yes i won a free package upgrade for May month she then advise that were the confusion is coming from the R539. 00 will be reversed but that has not happened instead i received sms reminding me to pay R539.00 01/08 i emailed Dstv again to query that i was told that i didn't pay June subscription and as far as i know if i dont pay they supposed to disconnect my service therefore I should not be in arrears with their account. I am very unhappy with their service and inconsistency. Reference number ***8 My customer number is ***7 Makekana Motloutsi
