Who called from 3604607730

I'm with Sprint not Verizon and I still get the calls

Keep getting calls from this number.  Very few people have my cell phone number so I did not pick up.

Do any of you attend or have any affiliation with Usdan?

I answered a few questions about age, diabetes, and sleep apnea, then they asked if I prefer credit cards, debit card, or writing a check. I didn't answer and it hung up on me. I called back and it says the  number is disconnected....definitely a scam.
