Billing / Unresolved queries

Queries/request to action items on this account were not done, did not receive any notifications whatsoever advising that the My limit would be reached before me reaching the exorbitant costs before the line was soft locked prior to it working in the previous months. Note I had to call Autopage to open the line telephonically as per their records, no further investigation has taken place since then. Refused to pay this account until resolution but none to date.Note that a migration and contract to be cancelled but this too has not taken place but yet the account is still billing. No recon been done here as well. Autopage too can't provide my signed addendum confirming that the data limit is not guaranteed. As far I'm concerned I have all my docs/records in place. Note that I've paid the account promptly in the past prior to this incident. Keep in mind I called in timeously to open the line monthly when my line was barred.I don't agree that info is accurate and now I've been handed over.
