was that date from Turbotax or the iRS refund website? If Turbotax, that was just an estimate.
when you elected to have your fees deducted from your refund or got an advance you agreed to have a third-party bank (TPG) receive your refund to split between what you owed Turbotax and your remaining portion. TPG sent on the remaining refund using the direct deposit info you entered on your return. Most users don't bother to read what they agree to and just scroll down and make the checkoff. The $1100 shortage is likely due to some error the IRS found. You'll be getting a letter from them in 3 weeks or so explaining what it changed.
you can send your complaint but it's without merit since you agreed to the process and the $1100 difference is probably due to your error.
