Who called from 8014135000

You get a call from number 631 (that is all you get) with a message to call 800-507-4275 and use reference number 261987.  When you call the 800 number you are instruced to call a different number, the 801-413-5000 number.  Reverse look ups show it to be the National Education Institute.

He recibido varias llamadas del teléfono indicado, pero desconozco de su origen. Me gustaría saber su procedencia y si repercute en mi consumo el aceptar esta llamada. Gracias de antemano.
