Cell C debiting money even after I canceled the contract.

I have 3 contracts with Cell C, two of which I started in 08/04/2023 and 26/05/2023 respectively. Both contracts expired at point on the 3rd of June 2023 I called to cancel. I was told I needed 30 days and thus my account will debited end of June. Which was fine, but now 31 July I am being debited again for those two phone, despite it being over 50 days since I called to cancel. Daylight ******* and if this isn't resolved I am porting my number and account.
