I was referred by Choice home warranty (CHW) to CNN refrigeration. The no. they provided gets rerouted to some individual and they are also in dark. CHW gave me another no. 480-469-6032 to call but that no was out of service. Like many other customers who reviewed here, i also check the BBB and they revoked the membership because they had lot of customer complaints and never resolved. Worst company as they give damn to customer service.
