I haven't received my 3 month code for grove music.

Where did you sign-up for the Microsoft Groove promotion? Was it on the Xbox One dashboard, or was it through Groove's website or the Windows Store on Windows 10? If you signed-up on the Xbox One dashboard, you came to the right spot!

If you signed up through Groove music's website, or through the Windows Store on Windows 10, please drop a post over in our Groove Music Support forums so the
proper team can assist. We're able to help out with promotions ran through the Xbox One dashboard, however any promotions outside of that we don't have access to unfortunately.

That clarification will help us narrow down the next steps. Keep us posted!

same here i signed up to groove music and haven't received my 3 months free

Hey there -

I did some digging and the only information I can come up with regarding a Buy One Get One promotion is here: Groove BOGO offer. That said, that offer expired back on August 17, 2016.
I'd recommend you head over to the
Groove Forums for additional assistance and clarification on the promotion you are referencing.

Thanks for understanding.
