In the UK, we have an app called WeQ4U which stays on the line for you while you're on hold. It rings you back when you finally get through to a person. Not sure if there is a US equivalent, but might be worth a look! It's such a useful app!
WeQ4U, free calls to numbers that usually cost a lot to call to. So good, has saved me sooooo much money! At least £50 over the time I've used it, it even told me!
