I need to close my account!

I need to close my account!

I have not been using Zoho for months.  I have been trying to close my account and Zoho keeps billing me for mobile edition.  I am really getting frustrated because I have tried many time to close my account.  It is a business account and I am the Administrator.  I log in and go to "manage subscription".  I went to "downgrade" and all apps/add ons are selected as "0".  When I hit the downgrade button it says "Specified users in the current subscription will be removed immediately though the expiry date of your account is 07/08/2012. Are you sure to continue?" I say YES.  It seems to process.  

Then I go into My Zoho account as the Administrator.  I choose "settings" then "close account".  In the "close account screen" it keeps telling me " Please downgrade your subscriptions from the below services before closing your account."

I have tried this several times.  Every time it does the same thing.  Every month you keep billing me for mobile edition.  I am really upset and you are ripping me off.  I want this program and the billing gone!
