Im not getting my return yet, it is under review, might have done something wrong, please call me, xxx-xxx-xxxx

When your return is selected for review it does not necessarily indicate that you have done anything incorrectly.  There is also, unfortunately, not anything that you can proactively do in most cases other than wait for the IRS to request additional information or complete the review. 

If additional information is needed, the IRS will request this from you in writing.

Should the delay of your refund be causing extreme financial hardship for you, sometimes assistance from the Taxpayer Advocate assigned to your area can be requested.  You can find your Taxpayer Advocate here: Taxpayer Advocate Service.
