First of all, sorry hear that. Second do not worry they will now straight approve you EAD and send you Interview call.
Unfortunately, once/if RFE is issues, it automatically delays the whole process by atleast 30-40 days.
I received RFE, and I responded to my RFE within 30 minutes (Online) and posted physical deliveray within 12 hours, still they did not change the status online about them received evidence till 30 days.
Just after 30 days, they straight changed three status, EAD was approved, deficiency notice was issued and Interview call was sent, all withing 48 hours.
