Yup they have fax service this PP Fax No. +1-402-537-5731 and i printed FAX sheet it content Case ID No. and Fax ID no. and other Information.
But for sending fax they were asking me to put the claim no and case id. May I know how did you find these info? Also, we need to create something called fax cover sheet to send fax. How did you do that?
