DSTV Ripoff

On the 12th February 2019 I received an email from DSTV notifying me of a price increase which would come into effect on the 1st April 2019. Within the email was a notification stating that if one paid the annual fee prior to the 31st March 2019 you would be able to take advantage of the current price and also get the 12th month free. As I’m a pensioner, I called DSTV in order to get the exact figure that I had to pay, and then took the money from an investment. On the 25th February 2019 I paid R6,589 as my Compact Plus annual fee, which would mean that I would only be billed again as from the 1st March 2020. Today I received an SMS stating that I needed to pay R150 by the end of December in order to continue watching. When I contacted DSTV today, they stated that they had kept me on monthly billing, and my cost WAS increased as from the 1st April. They claim that I should have contacted them to amend the contract period. I feel that I’ve been totally **********, as there is nothing in the adverti*****t that states that the client has to inform DSTV of this.
