Bad admin and failing to update account for two weeks

Cartrack tried to debit.my account.on the 14th December 2024 without any agreement with me, they send me WhatsApp informing me to make payment ...I made.paument on the 18th December 2024 , send them pop , they advise that payment will be allocated withing 48 hours...on 24th December they debited my account which makes two payments for December...I reversed the debit order ...since then is a back and forth as they can see my payment that I made on the 18th and promise that they Will delete the second invoice and update my account ...this has been Calls emails and WhatsApp for two weeks now...they want to tell me to.update the account takes more than two weeks?...worse part today when I follow up if my account is upto date they send me statement with cancelation fee of over 2k

I am not happy with cartrack.
