Tracker

I canceled my contract and monthly debit order approximately 3/4 month's ago..... This was accepted and confirmed by Tracker. Now and for past months I have had almost DAILY calls from their Collection Company, I have politely informed them to discuss this matter directly with Tracker, BUT they are still threatening me, not once has Anyone told me what is owing????!!!! But nothing is Owing as I have confirmation from HUGO from Tracker, that this matter has been resolved, canceled and is Over......... It's making me feel like a ********..... Never will I use Tracker again..... Very stressful experience
