Mtn

I app**** for an additional contract with mtn only to be told my application was declined. On further investigation as to the reason why it was declined, it's because my account is not paid in the due date. The reason why this was not paid in time was that an issue had to be sorted out by mtn. I took out a contract for my hubby and he was not happy with certain things that occurred and not agreed upon. So this was the only reason why the account was not paid on time. I have the first contract with mtn for more than 5 years now. I don't want to go to another provider. I feel this is so unfair that mtn has declined me for the additional contract. I don't have any debits and have no other debts. Can u please assist me in the way forward. I really would like this contract. Very frustrated.
