I've tried to apply for a car insurance with King price last month and then I canceled the insurance this month on 6 of July 2023. Which they try to debit their monthly payments and the debit didn't go through. So now I'm checking up my credit score and I found that they have blacklisted me because I didn't pay that monthly premium. So I don't understand why they put me through the credit bureau obligations...they must remove there
