Incorrect messages re: purchases

I had cancelled Fury Mazda Woodmead offer due to unsatisfactory service, however, I kept receiving multiple emails and SMS's from Mazda with "congratulations on the purchase of new Mazda 3". I've never bought the car and to receive almost 5 emails/SMS for a service that never been agreed on is depressing. If you could stop sending these "claims" and remove my contacts from your buyer's list, will appreciate that. Professor Irhuma
