I've worked in a market. Suddenly they stopped my work for verification purpose. They requested me to provide a student ID card. I've sent a scanned copy of my Student ID card for verification. One week has gone still now they have not sent any confirmation email. How do I politely and without any grammatical error ask them about my verification delay?
If I want to say something like this, is it correct?
Hi Admin, Why are you pending my Student ID verification? Why do you taking so long to verify my ID?
Here which sentence is appropriate in this perspective.
Why do you take so long to verify my ID?
Why do you taking so long to verify my ID?
Why does it take so long to verify my ID?
You can suggest some additional formal and polite sentence. Thank you.
