If you send it after hours you won't get a response. I learned this, but if you call tpg and ask them to look it up on your email address they can. I sent mine April 18 at 10:50 pm no response but then I sent it April 25 during business hours and got a response right away with a reference number. My check should be mailed Friday...I even had the post office hold all my mail so it doesn't be marked as undeliverable
