SAD Service from Platinum Life

After cancelling my policy at the end of January 2020 withPlatinum Life, you still go and debit my account at the end of Feb, why can you not get this right?, I had even gone so far as to discuss my cancellation with one of your call center agents and clearly thius info was not passed on. SO!!, please refund me thepremium you deducted from my account and pay the serrunder value of my policy.
