Called and I sent it to voice mail then called it from my work phone.  Says it a verizon wireless number that is not working.  Must be spoofed. Spam

sweat shop (phone room) many people talking in background  "SCAM "

Called did not leave msg.

Called to sell me viagra; foreign accent (indian?); POS telemarketer selling crap; spoofing the origin of his call

Exact same thing happened to me. They knew EXACTLY what I had been prescribed and began to ask me to pay over $300 over the phone but refused to tell me what company they worked for.
