Dotsure Insurance is a big ****

I did a car insurance quote with Dotsure Insurance earlier this year in April and their premiums were very high and so I didn’t accept the policy due to that reason but I believe I have been ****med by the same company because have been debating my bank account for the past 3months using Debit Check without my permission. Can someone from higher Authority investigate this matter with immediate effect because I know that calls are recorded and clearly somebody is ****ming clients within this company.
