Failure to respond/assist

I have sent the letter of authority.<br> Last week I phoned and the lady told me the documents will take 3 days to show.<br> Today I phoned to hear if it has showed on the system as it was submitted the 06/02/2015 by his old company, now suddenly the letter of authority is not correct.<br> But last week they helped me and did not have a problem with the letter.<br> All that we are trying to find out is if the have received all the required documentation for the claim. Because he is working early in the morning until late underground.<br> Horrible assistance<br> <br> <br>
