BIR 2316 inquiry

I was employed by TPG from January 2017 until April 19, 2017 then I moved to Accenture last April 21, 2017. I submitted my BIR 2316 (issued by TPG) to Accenture this month and received notice from Accenture that there will be a deduction on my salary due to the difference of my new tax. Now my question is, can I ask Accenture that I'm withdrawing my authorization for them to use my BIR 2316 form I submitted as basis for their tax computation due to a tax dispute from my previous company? If this is possible, will Accenture refunded me back the amount they deducted from my salary? As what I have read from a website I can personally file my BIR 2316 on April 2018 directly to BIR. Please enlighten me.
