********** contracts

After several attempts to get them to assist me I am so done with this company. I have been struggling since 2021 with Cell C. First, they blacklist me for an amount I apparently owed since 2016 but I managed to upgrade my contract every 2 years after 2016 without any hassles and no one telling me or them sending me a statement to notify me I have an outstanding balance on one of the accounts I have. My problems started when l I tried to cancel my contract in 2021. After paying different amounts that would make sure the cancellation is done and 4 months later the contract was supposedly cancelled. That's when they told me I owed them money, I eventually paid the amount they blacklisted me for because no one could help me.. that at least cleared the default. Two months ago when checking my clear score report I see another active contract listed by cell c... I logged a review, and they sent me a reply they cannot pick up anything on my ID number. Now my question is if I don't have a contract why do you list an active account on my profile. I sent their customer services emails in November, December and January. I called their 084135 number today and selects to speak to someone just for that *********** person to transfer me to their contract department. I eventually get through after waiting almost 10 minutes. I asked to please check why there is an active contract listed on my credit profile. I get a response there is no contract on linked to my ID number. I then asked her to check the accounts I apparently owed money which was paid to see if there is something outstanding on those accounts.. I all of a sudden have to answer a few security questions.. asking me 3 questions and of them being my ID number, this agent tells me she cannot continue with the call because I failed the authentication process.. I gave 2 possible answers to the other two questions because I might have forgotten the details seeing that I initially took out the contract in 2016.. She just refused to help me and ended the call. I am going to log a complaint with ICASA..
