Disappointed and tired

I am so disappointed with MTN provider , I phoned on the 26 October 2023 to cancel my contract and MTN said I must call in November after the debit order I then phoned on the 27 November 2023 to cancel my contract and the contract was cancelled same day , MTN they loaded airtime and data on my phone on the 26 apparently it was my billing day but the consultant by the name of Sebabalo Mphethi never explained how the cancellation work , he just cancelled the contract and when my contract got cancelled to prepaid MTN took away the data and airtime and I never used the data and airtime..now MTN is charging me airtime and data that I never used , MTN is taking away my kids money to buy bread , 😭😭😭😭 I reversed the money December and January I will never pay for something I did not use...all because of an unskilled consultant by the name of Sebabalo Mphethi...I am phoned MTN many times...I then phoned on the 5 February 2024 ... Lucky enough they transferred me to account and the consultant from account advised to transfer my call to Sebabalo Mphethi to send email for cancellation of the invoice because it was his fault not to explain the process of cancellation to me.... apparently Sebabalo was off that day ... The consultant by the of Yanga Nqesi answered...and he tried to cover for Sebabalo but he did not win .... He then called the manager by the name of Khanyisa ... Who promised to sort out the issue the following day but still waiting for I am so disappointed again by the manager by the name of KHANYISA , she promised to sort out the issue but still nothing is the second day today.she admitted that Sebabalo did not do his job properly by explaining the cancellation process.
