Worsed Cell C Service EVER

I am Itumeleng Madisha I have been using Cell C since 2014 when I did my first Contract with them...All those years everything was fine up until I informed them that I will not renew my contract due to financial contrains. I indicated to the via a call that I want my contract canceled I called them in November 2020 and I was told it is still too early to cancel the contract, they told me to call in December 2020 which I did then I was told is too early I must call them in January 2021 which I did. To my surprise the contract wasn't canceled but moved from month to month basis. They started debiting money from my Account without my permission. I went to the store and they promised to cancel the it but they never did they kept sending me monthly database and debiting my account. I then decided to Reserve the debit orders up until they canceled a month to month debit order. To my surprise I received a call from Cell C lawyers saying I need to pay them money which got me confused I never paid it. So they decided to block my number is been almost a week now unable to make or receive call. Today 20 October I went to the store to make inquiries I was told to do a Sim swap and was told to insert the new Sim card after 4 hours. I did the Sim swap at Cell C Menlyn.whn I put in the Sim card is still blocked. I need my line back on. I cannot tolerate this nonsense any longer. I am missing important calls. They must do something and very Fast.
