Stop sending me SMSes! I cancelled my contract with you!!!!!

<p>Two months ago I sold my vehicle which had the Tracker tracking device in. I'm still getting sms that my account is in arrears.</p> <p> </p> <p>I spoke to one of your consultants who promised to cancel my account. Please just stop it!</p> <p> </p> <p>Please stop because I'm not about to pay for a tracking device in a car that's no longer mine.</p> <p> </p>
