Can a CoS be reused if the worker withdraws the visa application

[somwouldnever]

I have a few questions regarding my application -
I am currently on a student visa which expires in october
Me and my sponsor were unaware of the fact that the start date of the CoS cannot be before my course end date. Hence once I submitted my application, the HO wanted proof of me having completed my studies. The uni won't issue a letter stating the same until the end of my course even though I have practically finished all my coursework and modules. My CoS status is still assigned as a decision has not been made yet.

I have therefore three options -
1. withdraw my application and reapply with a new CoS with a rectified starting and end date.
2. Withdraw and reapply with the same CoS but with a sponsor note stating the rectified starting and end date
3. Do not withdraw but issue a cover letter to the HO asking if the employer can still add a sponsor note with rectified start date, could the caseworker reconsider my application with a new start date.

Which one of the three options do you think is best for me.

Please let me know if any of the above three options are incorrect or contain misinformation as this is based on my own research

Thanks

Option 1 is the best and safest. That ensures you get a clean slate and no complications.

Option 2 - is a possibility but it has risks attached. The COS would probably go out of date anyway.

Option 3 - Home Office would not allow this.

We apply for the DCOS and Home office is asking for bank statement of the business account for last 6 months do anyone knows what they are looking for ? Are they looking for ending balance as we do not have very good bank statement ?

Any help will be apricated. Our company have 4th DCOS we already have 3 granted also we have more than 1 business account do we have to send the account which we are paying staff salaries ?

thanks

They might be looking for the previous payments of salary to the workers already sponsored. Or for viability to afford the next worker. It could be a whole range of things.
