Is there any way to increase the submission limit without upgrading the account?

Hi,

Today is May 28th. I have subscribe a plan few years now which is for 1000 form submission monthly (Bronze Package $19 monthly). For now, there are 991 submission already. I don't want to pay double for upgrade (Silver Package $39 monthly) which is for few more submission until this end of month.

Do I have any better option for this few days?

It seems you already upgraded to Silver plan.
