DSTV pay us or else!

This is my experience trying to cancel my DSTV subscription. My last payment was in March 2018 which settled my account in full. On the 3rd of May I received an SMS stating that I had stopped paying my account and that I needed to pay R949 to reconnect. As I had cancelled and owed nothing and did not wish to reconnect I ignored the SMS. On the 30 May I received an SMS stating that DSTV had not received payment on my account and that I was to pay R149.83 ??? I contacted DSTV's customer service to enquire what the amount was for and was told that a statement would be emailed to me. I then received a phone call from a DSTV representative who wanted to know why I had cancelled. On the 30th of June I had still not received the statement and now received an SMS from DSTV informing me that they were in the process of using an external collections agency to collect the outstanding amount. I then contacted DSTV customer service again and spoke to Daisy ref no ********** -I144. She informed me that I owed the R149.83 due to DSTV providing service for an additional 5 days after the end of the cancellation month. I informed her I never requested this, I never used the service and that i had cancelled. She informed me that they had no record of my cancellation, no record of my first phone call, no record of the representative that had contacted me and that I needed to pay the outstanding amount. I then requested to speak to someone from the billing department and was informed that i would not be able to since they are not allowed to transfer clients to the billing dept and they do not give out the number for the billing dept. She did however promise to request the billing dept send me a statement and confirmed my email address. She also mentioned I could view my account using MY DSTV online. To date I have not received any statement, when trying to view my account online, I login and then receive a message saying I cannot view my account since I am not logged in, even though the page shows my username. So to avoid being blacklisted, I am being forced to pay for something I never requested, something that should never have happened, from a company whose service I dont want, and I cannot communicate with anyone from the company that can say anything except pay us our money or else! So with no other option and to avoid being blacklisted over R149.83 I have been intimidated into paying the money. What an absolute disgrace, my family, friends and everyone I know will never have anything to do with DSTV ever again!
