Carmen: usted necesita llevar los platos. gabriela: estoy ocupada ahora. ¿puedo decirlo a carlos? carmen: ¡sí ¡ dímelo dígaselo díselo dígamelo

This is a formal command. The word dígaselo comes from the verb decir and includes an indirect and direct object pronoun written at the end of the verb. This is the case of indirect and direct object pronoun working together. Le is the indirect object pronoun that matches the third person singular and changes to se when working with a direct object pronoun. So lo is the direct object pronoun that matches the third person singular, too. Finally:

Carmen: ¡Sí dígaselo¡ dímelo dígaselo díselo dígamelo
