Insurer making cancellation impossible

I’ve been trying to cancel or as they out it - request to cancel my subscription for possibly 4 years and netstar continues to tell me it’s cancelled and say that they will debit for the last month as part of notice to only continue debiting. I’ve sold the vehicle at least 4 years back and informed them on various accounts which they seem to have no record of everyone I follow up.

I’m extremely busy to make daily follow ups but it’s frustrating to make a cancellation call and then see debit orders two months later and when inquiring they say account is very active.

This is for the same reason I no longer use a tracking g device since the service providers make leaving a nightmare and netstar at this point takes the cup even when you inform them that they have taken money incorrectly for over 4 years. This is unjust and completely misuses the trust of the end user.

When I raise the complaint they deny all knowledge of my cancellation attempts and keep reverting me back to the same call centre which I’ve possibly been calling for 4 years
