unfair rating and refused

recently went into an MTN store to get myself a new cellphone contract.<br> On making my application, i discovered i have been refused.<br> The reason that was given to me is because i may have an outstanding account payment, or in the past few month's cycle, a specific account of mine may have been in arrears,<br> Which to my knowledge is true.<br> I have a clothing account at markhams, which is up to date and at zero balance since October 2015.<br> Prior to that it was in arrears only because i was out of country for 4 months due to medical reasons and i had no one taking care of my payments. This should not be the reason, for me to be blacklisted or rated as a bad payer and being refused for getting a cellphone contract.<br> Till date all of my accounts and my dealings are clear and on par. The ITC can go through my track record.<br> I humbly request for my name to be cleared and also being aproved for getting my cellphone contract.<br> As i personally feel its not a fair rating and a fair decision towards me.<br> Regards
