Unauthorised transactions

<p>My eBucks points are decreasing every month without me redeeming them</p> <p>There's flexi save transactions which I have no knowledge of and when I called the call centre, I was advised that part of my points are contributing to my flexible save account. I didn't authorise such and upon requesting the reversal, I couldn't because my authentication didn't go through after numerous attempts.</p> <p>I don't want any link between the two... can I have it fixed because I never requested for it </p>
