Zoom-I-Net Communications, Inc.is a fly-by-night bunch of thieves.
File a formal complaint immediately with the FCC, your public utility commission and your local better business bureau. AT&T will say they can't do anything and they won't. Demand zoom refund ALL your money, not just reduce the charges.
They will lie and say that they had authorization to change your service, ask for a copy of the recording be emailed to your home email address; it will never arrive because it doesn't exist.Good luck getting these bottom feeding *** suckers to do anything honest or right.
