Second time I got a call from this number and it shows on my phone as "invalid Phone number". NO message has been left. Scammers, scumbags, ... I just entered it on my phone as "Spam #10" and designate it as a blocked call.
They called my cell phone. I got the "can you hear me?" to which I replied that I could and asked the purpose of the call. The caller said that their records showed that had problems with my back and shoulders. I told the caller that this was incorrect information and to not call me again.
I usually do not answer unfamiliar calls. This was labeled California in the caller ID. I have relatives in California, so I answered. I said "hello", there was a pause, sounded like connection, then the caller said "This is Jeremy, from Medical (sounded like brace, but was unclear) Promotions. Can you hear me? I said no, the connection is bad." He hung up.
