Debit orders that don’t belong to me go off my account

First of all I’m tired of outsurance debiting the account of my son and I every week when I don’t even have anything with them, I’ve tried calling them and they told me someone used my banking details to register their plans.

They promised to investigate, found out that it’s few people and then promised that it’ll stop. Still I’m always disputing the debits, it’s frustrating so much because aren’t they supposed to check if account details belong to someone before they debit that account.

How do you debit a 2 year old’s account? What they are doing is totally wrong more especially because I’ve never had any plan or insurance with them, and clearly won’t even in the future.

I feel ****med and they don’t care.
