Device Still being billed after 24 months

<p>This is a further follow up to my initial complaint which I posted on 20 February 2017.</p> <p><br />Thank you for responding to my issue regarding the erroneous billing of an additional handset beyond the contracted period which was signed for.</p> <p> </p> <p>I am pleased to report that the matter was dealt with and a credit note with reference CNI46193 was app**** to my account.</p> <p> </p> <p>I am however again dissapointed to see that on my latest invoice the very same handset in question was again billed to me errouneously. The handset in question is for an old device for which the 24 month contract has well expired.</p> <p> </p> <p>Kindly review my invoice for 1 April 2017 to ensure that the incorrect amount is not debited from my bank account again and please ensure that the device is permanantly removed from my account.</p> <p> </p> <p> </p>
