Not receiving my full refund

Hi Community,

 

I am filing with @TurboTax from three years. On both my 2nd filing & 3rd filing, I did not received the full refund they made at the end of the submitted netfile. On my 2nd filing, it was just $300 difference so i just left it. On my 2022, filling there was a difference of approximately $750 difference. So I contacted Turbotax maybe like more than 20 times, and every time they keep on giving me new investigation numbers and ask me documents which I have shared 5-6 times and never herded them back.

 

They hang up after keeping calling on hold for hours stating that they couldnt find a problem and that our expert will call you. And it never happened during the entire year. I contacted them recently again and still not herd back. Please guide, that should I case or any other solution to get my money back. 

THANKS
