No communication or too many requests for same info

Autio and General send a form to complete with all the details and information that various other consultants already have. When I send a message on the same email as a return message it is rejected so how can anyone get in touch with these people to find out why the same info is to be resent over four times. We respond to their message and then get the reply message rejected. The person dealing with the claim goes on leave and then we are bombarded with resend the pictures the forms etc.Question when you have the info why do you not get it from your departments instead of each person requesting again and again. Is this a delaying tactic. Appears to be.
