I was offered a job for UPS he explained my schedule and my job activities

Since you know all about the caller, why did you look up the number on a call complaints site?

Also, how did you know that was the REAL UPS that called?

Really??  What company would that be??  Looks like a preemptive shill alert.

This number called twice within one minute. The second time, they left a message. The lady had a very thick Indian accent. She said something about a job opportunity, greeter, and send me an email. Definitely NOT UPS.

Same as Eric, I got a call twice within seconds of each other. The caller ID showed up as Vanuatu (a remote island in the Pacific) The second time they left a 3 second blank voicemail and the caller ID said Stone Mountain, GA. Scammer I'm sure.
