Unpaid refund of premiums overpaid

I cancelled my tracker account in May 2015 but Tracker continued billing me until October 2015. I made inquiries with Jo-ann Brooks and I it was confirmed that tracker my refund and it will be paid out soon after numerous follow up she said that the matter was escalated to the Finance division which needs to repay the refund but even to day after months of waiting I have not received any feedback and my refund was never repaid. Is tracker also going to repay the interest that I have forfeited for the refund withheld? Your urgent assistance will be greatly appreciated as this is unacceptable business practice. The policy number is CLI*** and cancellation was for 2 Vehicles.
