I concur.
In this specific case, I’d have considerable doubt that it will solve the issue. They might follow standard procedure and just update their records and pursue Hippo8 - just as they’ve done with the address change. Intrum might not even know the date of birth of the actual debtor.
In any case, it’s unlikely there’s a button or process in their software that says “wrong person” and to remove his/her address as a false positive.
Frankly, I doubt that they care from whom to extract the payment - as long as they are getting money.
Could be a relative. Or even some neighbour living on the same street, who will pay it anyway, just for peace of mind and/or fear of the consequences (poursuite).
