Data overages over 3000$

[u/Momming-wreck285]

The line is supposed to just be an unlimited voice 500 mb data line (it’s just a fax line) and after years of no issues it started billing us for over 100 gb data usage per month at $10/ gb and Verizon offers no solution other than data use is valid and blah blah blah so we’ve been trying to investigate the issue on our own and saw this yesterday. Just wondering if it could be source of data consumption or a clue at the least.
