Yes, DRFs can be rejected by your DP or the Company / RTA. The reasons for rejection may be signature mismatch, incorrect holders name, certificate details mismatch between certificate and DRF, call paid receipt not attached, wrong formats used, old / defunct certificates surrendered for demat, etc. The rejected DRFs can be collected from the submitting branch or can be sent to the Investor’s address as registered for the Demat Account. Demat Account holders are informed about Demat Request Credits / Rejections through their Periodic Demat Account Statements.
