After 01/07/2017 , if mismatch of pan with aadhar for then Refund possible for LIC agents ?

One question ?

After 01/07/2017 , if i don't link Pan with aadhar for income tax return ( Or mismatch of link betwwen PAN and aadhar ) for my clients ( LIC Agents ) and mention only aadhar no in the income tax return form ( ITR 3 ) for AY 2017-18,

then do you think that they ( LIC agents ) will get refund for AY 2017-18 without any problem ?
