Frustrated client

I got clientele to assist me with the Claim for a Motor Vehicle Accident to assist us to claim from the owner of the vehicle that knock our vehicle and i have already had 3 different people who ask me for the same documents over and over again. i am sure all the documents that was sent to the first person will definitely be on the system as i have been using the same reference number on the emails to them and everytime i called. i am absolutely frustrated as my case is being pushed from one person to the other. however when they advertise they say that the legal team is always available to assist. also when they want their premium its already paid to them on time every month, but my case is being pushed from pillar to post with different legal advisors asking for the same documents. if they listen to my calls they will understand my frustration. i need to be assisted urgently
