How do I downgrade my account back to the free plan?

Hi, i'm trying to downgrade to the free plan, but not able to do so. error message says to contact you so i am. will i continue to have all the functionality that i currently have with my account? 

I see that your account is now holding Premium monthly subscription. The subscription is now cancelled and the account shall be downgraded to Free at the end of current subscription period i.e, on 2016-02-26. 

Once the account is downgraded to Free, you'll be able to access all the features available. However, please be noted that free subscription is limited to receiving only 100 submissions per month and the storage space is limited to 100MB. You may check our pricing page for comparing the plans available.

Hope this information helps!
