I submitted a claim for my mobile. Appsdaily informed me that original bill copy is missing in the courier. I have purchased the mobile from flipkart, so there is no such original bill copy. To share this information i have tried to there customer care so many times, but no one is there to pickup. Also i tried to sent email but the mail delivery was failed because of following error

The error that the other server returned was:
550 #5.1.0 address rejected.
