Poor legal service.

I had a Cell C contract till 03/2020. On 27 Dec 2019 they terminated the service due to an ammount I was paying off. After March 2020 they continue to bille me the contract value till 20/2021. Seeing that there is no more an agreement between us they removed the number from network . O was handed over to an attorney and upon explaining to th they said they will send it back to cell C. For a year now I am trying to get the 1 year subscription for 2 numbers reversed. Last case number *** on the 20th June I was contacted by them after logging the case they contacted me to find out the problem and will come back to me. I did a follow up and subsequently the only changeade was to remove the default from Experian and re-activated the numbers as pre paid. Now why did they not do that when the contact expired and not acumilate R10 000 in subscription not able to use. I just want their OWN legal team to contacted and resolve it not so difficult to do..
