MTN contract cancelation department does not want to cancel my contract.

Hi why is it so hard for you to cancel a contract my ends today, and I don't want you to debit my account any further, or I will take legal action to this because I called your cancelation department 1st time the idiot lady I spoke to said she processed the cancelation but I got no SMS to prove that on this was on the 2nd of June 2023 I called, on Friday last week I called again Spoke a a guy named Dillon, he informed me no1 done a cancelation on my account for number ***, and I told him I don't want month to month I just want it canceled then I got this SMS, "Y'ello! Your contract is set to be cancelled on 07/30/2023. An MTN consultant will be in touch to confirm this with you, or you can call customer care on 135. Have a great day!. as I am paying a bond now and cannot handle a upgrade or anything. Now today I get this SMS, "Y'ello! Your contract term has ended. Your contract is changing from R248.998 to R 104.348 on a month-to-month term. All promos have expired." I do not want to even pay R104,348 or anything I am broke.

Please cancel this contract because from the beginning I was given the wrong deal.
