They have faxed an advertisement repeatedly for months that uses up tons of our toner. They do it from a intentionally anonymous fax line so I can’t block them or fax back. We have gone on their website to unsubscribe. Same with a phone line they have. We have talked to two agents and a “supervisor” who say they’ll remove our number but don’t. We’re a health care office that can’t just switch our fax number. They are costing us money wasting our toner…while advertising us toner. And refuse to stop. It’s incredibly frustrating.
