MTN lack of response/communication

I am a very frustrated customer. I have been dealing with the cancellation of my MTN contract since August 2022. I initially went into the MTN in Cape Town, Cavendish Square branch and I was told cancellations cannot be done in store. They gave me a contact number and email. I called the number, sat multiple times to a tune in my ear with no assistance. After hours of listening to this tune I hung up as I’d done this for over two weeks. I then decided to send an email to the “customer care and/or retentions” email address but all I got were automated responses. I then called the MTN Branch in Cape Town as no one was getting back to me to confirm my “cancel contract request”. I called the headquarters in Johannesburg and they said on my records there is no reflection of my request. I asked the lady where all the emails went but she could not answer me and put me through to another person who could supposedly help, but no one has gotten back to me. I am highly disappointed and feel incredibly disappointed at this lack of care, or rather customer service. Up until this point there has been none! What’s the point of having all these so called assist platforms if no one can assist me? They’re never late on taking my payments though, but when in need of help, no one has answers or is non responsive.
