the scammers are cloning the numbers, beside they posting comments on various sites like this to make it look real. Also providing the real IRS collection phone number 217 785-2698 to make the things more interesting. I did not received any letters from IRS with saying that I owe something , so why they should keep bugging me over the phone. If You owe something,or if there anything missing in Your file they will send You letters with saying so, then You can call them or talk with Your tax person and solve the issue.
Also if you call tax collection number 217 785-2698 it says if you do not have the notice with tax payer number please call next time when you get one.
