EP regection Appeal

Hi there,
I would like to get some advises from all of you
On my current situation of EP rejection.

Received EP rejection recently and the immigration vendor informed that employer
Needs to submit financial turnover earning for past 3years to appeal my rejection.
This advise was given by MOM immigration vendor said.they did not share with me any spesific reason of the rejection.
My employer said that they updated financial document and now good to go for the appeal.

I understand that the appeal may takes at least 3weeks..My pass will expire on 29 July 2021.
I am very worry of my current situation and
I would like to know if there is any way that we can shorten to wait appeal result.

Thanks
