Cell C review: I am currently blacklisted

I had a contract with Cell C. When contract was in time to be ended I was in store to terminate it. With alot of excuses the changed it to a month-to-month contract. After a time I went in store to terminate it. They changed it to a 24 month contract without my concent.

After the time my debit order was triple the amount it used to be. they told me instore my contract was ended so I am paying normal price for data.

I asked them to terminate the contract, stop the number, cancel me from their system. They gave me a print out to ensure it was done. after a couple of months they still debit my account. I went to the bank and stop their debit order.

Some attourney contacted me regarding payments. they never provided me with bank details. They handed my documents back to Cell C. Cell C handed me to a new attourney. They can`t find my details. What am I to do
