MISSING OVER HALF OF MY TAX REFUND !!!!

I filed on Turbo tax on the 2nd of February 2022 . My full tax refund is supposed to be $5200. I only received $1800 in my savings account , I am missing exactly $3400 of my tax refund! I do not owe any money to anybody or any service so there is absolutely no reason why I don’t have my full tax refund in my account. I called Turbo Tax on 3/12/2022 and they told me they can’t do anything about it that I have to call the IRS, which I did but yet I can’t get threw to them for some reason. The IRS literally hung up on me with any line  I tried to get threw too to them on. I have not been able to speak to a single real person over the phone with the IRS . I need the rest of my Tax refund ASAP please and thank you !!I need help!!
