Client: I didn't want my refund check, so I sent it back. I didn't even open the envelope, so I wrote not valid and sent it back. Now I want that refund check and I have a hold...why is that?
Me: Well, when you sent that check back, you wrote "not Valid" in turn we assumed your address was not valid and we had to stop all future disbursements and refunds due to that. In turn, until you fix your address, you will get no Financial Aid.
Client: Oh...is that bad?
