Debiting without debicheck approval

On the 23rd of June I opened a funeral cover online using standard bank app stating that they can take the 1st premium on August but to my surprise the debit order went through without my consent, reasons why I am saying that,the debit order went through without my consent is because of I didn't approve their debicheck trying to avoid such incidents. The question is,can a debit order go through without approval of debit check and also who approves online funeral applications.
