Why is my account over quota?

There are zero submissions currently but the form is showing quota over message. 

Hello manikanth,

I did check your account and found that you have received 120 submissions this month. It seems you have deleted the submissions from your form. Please check the screenshot below:

To activate your account again, you will have to upgrade your account or wait for the first day of next month when the submission counters are reset. You may like to take a look at our pricing page for more information on available plans and its limits:  www.jotform.com/pricing

Thank you!
