Dear Experts, We have removed export of excisable goods under claim for rebate of duty. We have received original copy of are-1 from Custom authortiy but they denied to give duplicate copy of are-1 and said that we will send directly to excise department. Now the excise department has denied to received any type of are-1. The Department has denied the claim for that are-1. Now, please advice what can i do for receiving the claim. Thanks
