After you file

I've just been told by a TPG representative that 50% of users "provided incorrect bank account/routing numbers", causing the process to be delayed due to the manpower takes to print, address and physically mail each paper check. What a load of BS! You really expect us to believe that that many people incorrectly entered such an important sequence of numbers like that of their bank account?! I know for a fact I entered mine correctly, yet their telling me there's been a clerical error. Sounds fishy AF!
