Scammer "returning your request for information about a medical back brace." Definitely a scam as 1) The caller ID has no name, nor is the company name given in the recording; 2) Neither I, nor anyone here ever requested this information; 3) They are in clear violation of the Do Not Call act (of courses, scammers are criminals and pay no attention to regulations.) Block the number and do NOT give them ANY information.
They called but left no message. Legitimate companies should leave an identifiable Caller ID (instead of simply location) and a short message about the nature of the call. If they do not comply, I block the number.
