Who called from 5014364069

so i look at my phone and seen this number listed in my miss calls section for 8 times called back but no anwer does any one know why this number will call a highschool student for.

So they called me 5 times and as i answer it they hung up

Called two days in a row. I answered today and no one answered on the line and then hung up. I tried calling the number back and received a busy signal

as soon as i answer the Caller said, "Thank you and goodbye.  like really all i said was Hello.

Wrong number
