Appalled by service (lack thereof atleast)

Data disappearing, contract price increase, No network coverage for most of the times load shedding, bills sent to incorrect email address despite going in to update 4 times, finger prints the works, can't place or receive calls in this time, wait and wait and wait for feedback from consultants regarding upgrade (Since December 2022). Going in to the store since my two years are over on the 26/04/2023, would like a form to give notice of my intent, since I won't be renewing my contract based on the above. What a shlep, still no answers and no assistance. just a call the help desk on 135 that doesn't ring or go through(but they won't help on weekends) Worst service ever, so disappointed I am forced to pay for this nonsense. Wrote the CPA and awaiting guidance on what steps to take next.
