Refuses to refund me after incorrect debits two months in a row

<p>I have been incorrectly debited 2 months in a row on my TFSA.</p> <p> </p> <p>The customer service agent refuses to refund me and wants me to go to my bank to request a letter. I refuse to do this as other companies happily refund if they are at fault.</p> <p> </p> <p>I have asked twice to be called by a manager to discuss but again, the agent refuses...</p> <p> </p> <p>Please sort this out as it isn't doing your brand any favours...</p>
