I have received several calls from this number. When called back it says "Welcome to the Kaiser Permanente Refill line," then instructs you to enter your Kaiser ID or press 2 to speak to a pharmacist. If you press 2, the message then says that is an invalid option.This is a very strange call. First, if Kaiser calls you, they are identified as Kaiser Permanente, not just Aurora, CO. Second, I have been with Kaiser for years and the pharmacy never call you, nor is that the Aurora refill number. Out of curiosity I tried calling that number several times to see if "2" is ever a valid entry (no) and now all I get is a busy tone. Possibly some kind of failed scam. If you are a Kaiser patient and receive one of these calls, it's probably best not to ignore it and call the number on your prescription bottle (completely different) or go online for refills. Just a suggestion.
