Worst customer service

I did an upgrade on my daughter's phone contract 24 months ago on 9 Feb 2021 and now when I want to cancel because telkom is expensive and I'd rather take my business elsewhere they are telling me that my contract can only be canceled in May 2023. However the contract was upgraded in Feb 2021. I have been calling telkom for the past 3 months and I was told that I can do the cancelation and I was given a reference number when I called again I was told that the reference number doesn't exist. I have been to multiple telkom stores and no one is able to assist everyone just directs me back to the online portal. I have asked so many times to speak to a manager and I was told that a manager will call me back to no avail. This level of service is disgusting. I have been paying 24 months and would just like the opportunity to cancel the service that is currently paid up. The representatives are rude and not helpful at all. I would not recommend anyone to take contracts with telkom ever. They offer the worst service and no one is willing to help.
