Standard bank upgraded account AGAIN with out my concent

If I have an option to give no stars then I will choose that. My account was upgraded again without my authorisation and then Sandy Begg have the nerve to wrote that I gave telephonic concent on the 14 Dec 2020. And just like the previous time they need to escalate the matter to the manager. That took me 3months to sort out on my airtime. You can call me before 9am or after 6pm. And I need an answer and correction on my account by the end of 6 January 2021.
