Affidavit of support fee exemption?

[RonMari 6]

I just received a notice from the NVC stating, "The request for an Affidavit of Support fee exemption has been DENIED."  I paid the online fee for my I-864, and there was no fee for my sister's I-864A, as she is a household member helping with support.  I did not request any kind of fee exemption.

I don't understand what this is about, or how I am to respond.  

Has anyone else ever received a similar message?

When responding to NVC,  u include your case #, both names and both DOB's

 

you simply write a statement saying:

I received notice in error saying my request to be exempt from fee for I 864 

I have paid the fee and did not request the exempt 

 

Make a copy of the notice and your return statement for your records

Errors certainly, not this one, presume wrong button pressed.
