Poor service is resolving billing issues

<p>I cancelled my MTN Cellphone Insurance on the 20th of February 2017 and to this day MTN is still billing me for the cellphone insurance. I have sent an email to customer care in order to get the matter resolved and received an email from Sabrina Hargreaves at Pinnacle Marketing requesting that I send through my billing statements and a detailed explanation of my issue to ********** which was on the 9th of May 2017. I sent throught the documentation and I still have not received any feedback to date. </p> <p>I need to escalate this because this is unacceptable that nobody is assisting on this matter. </p>
