Account Details

I have purchased Bronze Package first that is for 1000 submissions then upgraded my account to silver before one month. you guys deducted around 2 USD in first place then showing status for total 10000 submission. I have purchased total 11000 submissions. where are my remaining 1000.

Your account is currently on the Silver plan. The limit for the number of submissions that can be made to the forms of an account in the Silver plan is 10000. Please note that if you have purchased a Bronze plan before, this does not mean that the limits will get added up.

The limit counter is reset on the 1st day of each month. You can learn more about the account limits in the help article below.

When you upgraded to Silver from Bronze, the unused time of the Bronze plan was used as credit in your invoice https://www.jotform.com/invoice?u=nomanaziz90&id=2018-08-20_03:07:59, so, $2.55 USD were deducted from the Total.

Then why you guys have charged me again. 

That is because you are subscribed to a monthly plan which will charge you monthly until you cancel your subscription.

I can see that you have upgraded to the Bronze Monthly plan on July 24, 2018. This means that the next billing date for your account was August 24, 2018.
