These telemarketers are pitching medical supplies for a Florida company with a BBB rating of "F". Here's the url for contacting them: https://www.beyondmedicalusa.net/crm.asp?action=contactus
However, don't get your hopes up. I just spent time filling out their online "contact us" form and when I hit "Send", I got a 404 - file not found message. So not only are they routinely hiding behind dummy phone extensions, non-working call back numbers, sales reps with fictitious names, etc. etc. -- essentially all of the annoying tricks of the telemarketing trade -- but they've also constructed a website that doesn't allow you to reach them either. I've been getting calls from them for months. It was really getting under my husband's skin so about two months ago I wrote/mailed a certified letter to the FL atty general's consumer protection ofc and the phone calls stopped cold. Today I got another phone call from 800 787-6410. I went to the Beyond website and tried to email them. You know the rest -- see above. P.S. I will send another letter to the FL AG's office.
