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.
