Has anyone had success contacting sales re: RMA's ? Have been waiting on a response for an RMA on 3 bad h-cards

RMA issues aside, these rigs are beasts once they are configured and placed in an environment with proper cooling ! The one full rig I have up and running has settled around 535 GHs !
I did have success with my RMA. After submitting my Oct 31 RMA for one broken H-board, Yvonne contacted me via email on Nov 12 and the replacement board shipped the next day. I received it yesterday.
