Suspended contaract after debit order went through

I have 2 contracts with MTN and after my upgrade in February they keep suspending my service. I barely had my phone when they suspended me, so I called 808 and they said I had to do an increase on my account so I did...A month later they suspend me AGAIN and it was the same story about having to do an increase. Then a month later I get suspended AGAIN this time something about a form that they did not receive with my upgrade, so I went to my MTN store and they filled in the form and uploaded it or sent it. Now this month again I get suspended. But they keep suspending me After my debit order went through or right after receiving my minutes, data &amp
