Who called from 5142880420

They keep calling me I am on do not call list

just called...thought it might have been a friend but good thing I procrastinated long enough to not answer.

They called on my cell phone and said it was a survey for American Power Conversion (APC). I refused to answer the survey.

I keep getting calls from this person. Who is this and why do they keep calling my number? Why dont the phone company do something about this?

Called at 2:40 pm, no message
