Earlier if i want to change my BSNL Broadband combo plan! I usually visit in person to the bsnl circle office to submit the request. Now no more hassles of visiting and waiting for any plan changes.
Here we go to submit the plan change online and it just takes 3-4 days even though they say it will take 2-3 weeks if you apply online. Usually manually submission will take less than 2 days.
In my case I submitted request online to change from limited plan 600 to unlimited plan 900 which took just 3 days.
Note : you may not get any alerts or any other communication that your plan has been changed. You need to check that in your account portal online.
In the account portal, you can change plan, submit complaints, check you billed and until led usages etc.

Hope this helps for someone.
