I'm trying to get set up to pay my Edenorte bill online with PagaYa. After I indicate it is electricity bill with Edenorte, it is asking me for "Nombre del servicio" in the field just before it asks for my contract number. Can someone tell me exactly what field on my service contract I should copy into that box? I've tried the obvious ones but apparently it does not match what the system is looking for. Thanks for any advice.
