poor service and faulty systems

For the second time my airtime has been depleted for no apperent reason. I spoke to 4 different consultants, who gave me 4 different reasons, i eventully requested for a manager (Ashly) but he too blamed me for the depletion but failed to give facts. He did not even offer to investigate the matter and eventually told me he cant do anything further, even after i threatened to close my facility..clearly shows that i mean nothing to this rich company..im just a number.
