Late Husbands contract#2

EC-1ZQ9-3V1KWZ part 2 I wrote how we struggled for almost a year to get correct help to cancel my late husbands contract. Finally someone managed to give me an email for the legal department. The response was shocking. I have been paying a contract for something that was not in use for almost a year. The total cost of that is around R6000. So now (during lock down AND without means to these kind of funds and withou any desire in my heart to even pay 1c further) they have given me the option to keep the number and use it as a pay as you go if I pay another almost R3000. I have 7 days to do so. If you do the maths it will then have cost me almost R9000 to cancel something that was not being used AND to keep the number as a pay as you go number. How do you justify this? There should be some law that protects consumers against this?
