Incorrect suspension of account !

My MTN service was suspended due to an amount I supposedly owe on my account. Yet I have been paying more on my account than the actual amount that is required. Which should have caused my account to be in a credit.

I do have proof of the payments made. I have requested statements for the time period to compare the records. But up to date none has been received. I am also currently blocked from the system, thus I can't obtain the statements myself. This so frustrating.
