Tax Advance

I filed with turbo tax the past 3yrs.Jackson Hewitt b4 that never been denied anything... This year file with Tt and filed for the advance and was approved for 750. Well taxes was accepted but no advance. Was told to wait til the 27th... still nothing. I called today and can't get a straight answer. I have had credit karma for about 5 years they won't help either. I could have put my stuff with my original bank. Who can I contact for info??
