Confusion in submitting Tax due to ITIN pending for my kid

Hi,

My name is Neeraj Kumar. I came USA in 2019. I applied ITIN for my three year old daughter so that i can get TAX rebate. My problem is as follow

I applied ITIN for my daughter in first week of February-2020 by myself. I showed and submitted the documents for ITIN in the IRS office situated in downtown Atlanta, GA. I get letter in returns. In that letter below three points are mentioned
The ITIN office will review your application package and will send you a letter regarding the status of your application within

Option #1: 7 Weeks
Option #2: 9-11 Weeks (Peak processing period of January 15 through April 30)

The letter will advise you one of the following
1. The letter will tell you an ITIN has been assigned. You won't need to take any further action.
2. The letter will tell you your application has been suspended. You will need to provide additional information to the ITIN office Austin. You may submit another type of identity document or documents generally. This Taxpayer assistance center will not be able to assist you further and you will need to respond directly to the ITIN office in Austin.
3. The Letter will tell you your application has been rejected.... and so on

The have also provided a contact number in case of any query which is [phone number removed].

 

Now it's been almost 4 months but i did not receive any updates from IRS office. Neither Approval letter not rejection letter. Now the problem is this if I file tax without adding my daughter as a dependent then some tax will due on me around $300 and if I add her as a dependent then it asks for either SSN (which is not applicable in my case) or ITIN which i'm waiting for.

Can someone please suggest, what can i do as i have to submit the tax by 15-July anyhow.
I tried to call the customer care number provided but not able to connect any singe time. Can someone please tell me is there any other way to know the status if ITIN.

Thanks
Neeraj
