They have provided wrong address for paper filing of the return which I was require to do for my specific case. I waited for 8 weeks to receive my refund. Then I came to know that the address appearing on their website for Iowa return is wrong so I was required to resend on correct address. On complaining about the same, they just came back with correct address, didn't also feel for apology. Had I not crosschecked the correct address, I would have kept waiting for months together. Support team doesn't go in deep to your question & just reply by seeing first or second line of your query. I wouldn't recommend anyone to use this service...
