Who called from 2503728103

Why didn't you give me a message ???

This number keeps calling.  No message  I am on nocall list

This number appeared as a missed call.  When I tried to call it "NOT in service".
Wierd

I keep getting calls from this number. Don't know who this is. I want it stopped

Je reçois souvent des appels de ce numéro et il ne laisse jamais aucun message? J'aimerais savoir de qui cela provient puisque l'on ne peut pas rappeller i, il demande le code régional. Merci
