Vodacom modern day ******** - after more than 20 loyal years of support they broke all my trust

absolutely filthy service, firstly they without consent put (up sell products ) ********ly on ones account and do not stop a contract that has ended over a year ago and assume you want month to month and when queried simply told no please settle accounts. i took out a laptop contract for R600 as per agreed to find they added top up airtimes etc amounting to close to R1000 then when queried no please pay then we talk. They then combined my cell phone contract which ended 2019 (paid in full) they upon many requests to stop top up incentives as i did not want anything and cancellation of cellular insurance they continue billing me and now soft locked a phone which i have paid in full already told me that they will continue billing me without fail and that the data will remain unusable even though I had not consented any of this at the initiation of contract the only item I agreed to was my laptop payment of R600. How can you ********ly put up sell products or put a month to month addition on a paid up account it is ******** I am in contact with the ombudsman and will take legal action, none of this was explained or emailed to me that you can put add on products on my contract debit me and then stop my service because i refuse to pay for things I did not agree to
