About a 50% shill rate is pretty good evidence that this is a scam of some sort. Ignore and block this number and DO NOT give out any personal informaiton.
This number is legit. I handle medical affairs for sibling and they called with a reminder for payment. I thought i had already done so. I am pleased that they would call with a reminder. Better than having coverage being cancelled. This is especially helpful given most of the people covered with this insurance we have are over 65.
This number called, left no message. I blocked my number, called them back and they said they were United Health Care's Financial Department and started asking for personal information. I hung up and called United Health Care's listed number of (888) 867-5575 and they told me they had no record of calling, or reason to be calling me and I did right by not giving out my information. They also said if they Were to call, they would leave a message with the reason why they were calling.
