H1B RFE received - Quota Full?

H1 was picked in April 2019, and also an officer visited my office and verified all my documents in August and I haven’t heard anything after, so I applied for premium and now I received a letter saying that they cannot proceed with my application as the Quota is FULL.

Did anyone had the same issue and how should I proceed further.

Sounds very strange, quota is full ? Did your attorney get any letter saying the same ?
Can you share the letter by removing your personal info here once ?
