Unhappy billing

Hi, on the 26/06/2019 I paid my DSTV account of the amount of R250 as my account was disconnected. The call center agent who assisted me said the amount I owed and re-connection fee as well as the July subscription would be about R250. Today i received a sms that they account has been stopped and to my surprise i called the DSTV and it says i owe R136.96 due on the 31/07/2019. I cannot understand what I paid for and why i have been disconnected. my customer number is ***.
