Just called and WOW, left a message.
Advised that it was for a free Rx review from United Healthcare. Funny thing is,  I don't have United Healthcare.
Left a number for me to call back at 1-866-216-0198 to speak directly with a pharmacist.
A review of the 1-866-216-0198 number clearly shows it is a SPAMBOT number for numerous calls for every kind of SCAM.
Don't think I'll be calling them back anytime soon.

Have received 4 calls over 4 days. They don't leave a message. Obviously spam.

Spoof number, scam from another high school drop out using united healthcare to try and get call backs.
