Be careful how you say things. You say you're an independent contractor in one statement and in another you say you essentially received a salary every week. Be consistent and accurate.

They have nothing to gain, only to lose. They are required to file a 1099 on non incorporated entities and exposure themselves to a small penalty if they don't file as required. I say small because the penalty is like 25 bucks per each not filed. So if only one it's not much but it could add up to a much bigger number depending on how many they should have filed.

That said, you can't force them into giving you one. Just tell the state that the company refused to provide you with one. Show them any schedules and correspondence if you have any and also show them the prior years 1099 and tell them nothing changed in you status. Your additional substantiation is that you included this amount on your federal return and paid all the associated taxes due.
