MTN De*****s customers data billing accounts

Once again I have tried contacting MTN to find out with MSISDN is being used in the Nokia Lumina IMEI: *** and have been told that MTN can NO longer track IMEI numbers which I find surprising unless you have downgraded your systems from Eppix.<br> <br> I also do not believe that my line should keep being suspended when I am still paying the monthly subscriptions I have signed for.<br> <br> I also have not received any response to my previous response on HP asking the exact same thing.<br> <br> I refuse to pay for something that I did not use and cannot get proper assistance with. If this continues I will take serious action against your Service Providers lack of assistance.<br> <br> Regards<br> <br> Terrin Livingstone<br> ***
