DStv (MultiChoice) WORST service provider in SA

I've been trying to get assistance, for the past 3 months, from DStv / Multichoice with no luck!

I've been trying (since 31 July 2019!!) to cancel the insurance on 1 of my decoders, being used by my mother-in-law. She was a resident of Alan Woodrow Old Age Home and moved to a new Retirement Home / Frailcare Centre. We have instructed DStv to cancel the insurance on 31 July 2019 already! If my math doesn't fail me, it is 3 months to the day. How can this be seen as acceptable? Numerous Multichoice employees have stated it takes 48 hours to cancel insurance, yet it's taken 3 months and it is still not cancelled! We can't reconnect, due to the decoder not being removed/cancelled from Alan Woodrow's insurance package. An 87 year-old lady has been deprived from watching any DStv programs (for the past 3 months) due to DStv's incompetence and lack of support and service. I expect this matter to be resolved before close of business today.
