Pathetic customer service/ arrogant consultants

I was contacted by Dstv/multichoice explore or supervisor , explora department during December 2018 for a special on dstv compact, suddenly the price has changed and i was never this as this was a 6 months special. I phoned to find out on the 23rd and i was told someone will call me back. however today l was rudely and interrogated like i was stupid by one of the consultants She was so arrogant and shouting. I told her i called 2 days back and i am still waiting for someone to call me back. Clearly there must be some record somewhere but she was so rude and interrupting me while i was trying to explain . I then asked her to not to shout and stop being rude, she still managed to apologies in a shouting manner. I then asked to speak to the Manager or supervisor she put me on hold for almost 20 minutes only to come back to me saying they are all in meetings and will call me back. i kindly want my service disconnected. Multi choice has made it and clearly don't need my peanuts judging by the treatment and business conduct.
