The incompetence that is MTN SA

I had a data contract with mtn for the past 24 months. the contract ended on the 11th June 2022( the story of how ****y the contract was is for another day 😡) , I called mtn this afternoon to cancel the contract since it’s standard procedure to cancel a contract that has come to an end 🙄🙄So I was on the phone with Mtn for an hour and half and I did not get help. I was only told I am liable for another 2 months of payment, and I have an additional balance of plus minus R980 and when I asked what is is for the two consultants I spoke to told me they are not sure 🤔🤔and they will transfer me to the billing department. Both attempts to transfer me to the billing department failed dismally and an hour and a half later when i called I was told the call centre is closed 😏😏 Is anyone is frustrated as I am with mtn?
