Inquiries, get hits on credit report removed deleted off

I have approx 10 hits on my report from gettting information on refinancing my home. I was just shopping for the rate and terms I wanted and no one would give that to me unless credit was checked.
One of them told me that those hits had to come off by owners request after 30 days if I did not use them to refinance.
Is this true, or some version of it? How do I get them off?

If it is I appreciate knowing it, but it does not sound right.
On the other hand you might be able to dispute duplicates.
I am not sure how to find out even other than try.
So why don;t you try and let me know back

Might just add a 50 word or less letter along with the dispute form
state which ones you want off.
