If it shall appear that an amount of surcharge has been paid which was not due under the provisions of this chapter, whether as the result of a mistake of fact or an error of law, then such amount shall be credited against any surcharge due, or to become due, under this chapter; provided that no amounts erroneously paid more than three years prior to the filling of a claim therefor shall be so credited. Ninety days prior notice shall be given to the Emergency Telephone System Board on any credit against a surcharge due.
