I was accepted in march and have not recieved my refund i check my status everyday but today my status saying information does not match i dont know why

Was the IRS "Where's My Return" tool previously saying your return is "still being processed", and now the IRS  tool can no longer find your info?    If the IRS tool had previously found your info and was showing your info, then you at least know they received your return and were working on it.   If it suddenly is not finding you, it may mean that your return is moving into a different phase of processing, and the tool may not be caught up.   That tool can be squirrelly sometimes as a return moves through various stages of processing.

NOTE:   Be sure you are entering correct info.   When using that tool, be sure to enter the correct SSN and filing status.  Use only the Federal refund amount, and not any total refund amount that includes a state refund.  The amount to use is on your Federal Form 1040, Line 21a.

You can also try phoning the IRS refund hotline.  I've seen it work for some users before when the WMR tool didn't.
