Annoyed by bugging emails and 3 debits on 3 different days!! Very high premiums

For over a month now we have been requesting for this service to be cancelled but we keep getting emails about installing this vitality drive sensor thing in which we don't want it, reason being how does your company operate when it goes into my account 3 times on 3 separate dates to debit? The premium is more than R8500 when I calculate those debits it's why I requested from the financial advisor Renier Van Der Linde to cancel this thing long before the 1 August 2018 and to date still nothing has happened, they keep trying to debit my account. Please stopas I'm happy with my current insurer and their premiums are much better compared to this ****************!!! We've cancelled this thing long before it started, please stop sending us all the things because we not interested, contact the financial advisor to resolve this as it's becoming frustrating everyday emails about this sensor which is no use to us.
