Hi there, I'm sorry to hear about the accident with your drone. Please submit an online repair request via https://repair.dji.com/repair/index and send it in for service. We'll do our best to help this out.
Having had a minor crash with my Mini last year, I have some experience. I sent my Mini into DJI. I was pleasantly surprised with both the repair time and the cost.
Normally I would try to fix that myself with parts available. But a DJI repair might be best in this case because of the delicacy of the gimbal suspension.
