Why the Inland Revenue's Online Self Assessment Tax Return Submission Sucks

*****STRONG LANGUAGE*****

I don't fucking believe it!

I'm on the phone to the fucking inland revenue on a courtesy call from them telling me that they've not received my tax return.

And on my screen is the pdf from when I did it on 12 August

Fuckers

They've no record of my tax office address and no means of telling me where my nearest one is for me to hand deliver it given that the filing deadline is tomorrow.

IT'S NOT MY PROBLEM!
