Hi there, @sunilsudarshan!
From what I am gathering, you are currently on a billing cycle that is longer than the monthly cycle (annual, biennial, or longer).
If this is the case, downgrading your plan cannot be done within the admin yourself. You will need to reach out to our live support team to make such a change in your account.
Feel free to use this link in order to speak with one of our live agents. If I somehow misunderstood your inquiry, I look forward to hearing more from you so we can assist you accordingly.

A billing cycle, also referred to as a billing period, is the interval of time between billing statements. Although billing cycles are most often set at one month, they may vary in length depending on the product/service rendered. Typically, the billing cycle lasts anywhere between 20 and 45 days.
