They were hoping you would give up so the agent could send the check to himself.
I still have the letters and paperwork filed away - just in case - they say there was an error and reach into my bank account and seize funds from me...which I think is a total Nazi tactic! I wonder how many people that filed and were entitled for this credit didn’t get the initial letter...they only had 30 days to respond and get the paper work in...after 30 days if the IRS did not CONFIRM they got the paperwork - then the person was SOL...sounds like a scam set of regulations....I didn’t stop until I got that letter...it was like day 20 when I was confirmed...pretty sad state of affairs....
