Billing query not attended to

<p>I logged a query regarding being double billed for my recurring data bundle (reference ********** 5678).</p> <p> </p> <p>I have called twice to escalate this (the last time being 17 November) and was advised that I would be contacted within 24 hours, I still have not had any update.</p> <p> </p> <p>In addition to the double bill, I am being charged for out of bundle data which is not possible as there is a recurring data bundle that has not been exhausted so there should not be any out of bundle data charges</p> <p> </p> <p>I am sick of waiting on hold for half an hour at a time and still not getting any feedback</p>
