Don't be so sure...

I got this call as well claiming it was CVS Pharmacy and wanted me to enter my birth date.  I called back and it is fast busy.

I received a call from this number when I was not home. The voice mail was reminding me of a delivery from Home Depot. I don't recall ordering anything from Home Depot so I'll just have to return the call tomorrow. I never know what the hell I've done or what appointment I've made. It might be legit. I do have a doctors appointment and a dental appointment this week but not on the day of this supposed delivery.

It was CVS calling about a prescription.

Got a call saying it was Centerpoint Energy reminding me that my bill for my gas service was due.
