Call harassment

hi

my contact lapse last year November 2020.i did informed cartrack in writing that i will not continue with the contract.

they failed to cancel my contract and continue to debit on my account which i reverse it back and block their debit order.

my contract was cancel on February 2021.

Please stop calling me everyday and demand payment,is not my problem that your staff failed to do their job and cancel my contract on time.

one of your staff told me that she will phone me everyday until i make payment.
