Cell C Service

I opened a Cell C contract Des 2020 for 24 months, debit orders never went off in time and continuous calls to contract dep, they keep telling me they've got technical problems, my premium is R249 pm and never took monies for 3 months, I keep phoning them and spoke to contract dep where all operators give me the same excuse and they'll get back to me which never ever happens. October 2021 they took without contacting me R746.94 out of my account, never took November and December R637.96, then I called them to confirm if my contract is now in order and they told me that everything is up to date, they changed my debit order date without my concern from sixth (6) of every month to the tenth (10), this morning Sun 2022 01 09, I went unto my Cell C app to find the shock that I owe them again R637.96. I immediately contact them and they told me I owe them R637.96, when I calculated all the amounts it's more than R2000 being taken out of my account in 3months, I'm very very unhappy with the service of Cell C, they full of empty promises all the time and each and every operator tells a different version when contacting them, I was insured by previous operator that my account is now fully in order, but this morning AGAIN a different version, I never will recommend anyone to take a contract with Cell C, I asked on luminous occasions for supervisors or management to contact me and that even doesn't happen, a contract that is now one year old with a premium of R249 pm is now costing me more than R2000 in 3 months with the very poor service of Cell C...
