Problem increasing my account usage

Problem increasing my account usage

Hi

I’d like to increase our monthly account to the 100 users for 1 host 

But I can’t seem to do this for just the one month, it only allows you to subscribe yearly as the billing cycle

The website says Zoho Meeting is a pay as you go (monthly or yearly) service so you can upgrade, downgrade or cancel at any time. Yet you only have a yearly payment option

any one have any ideas on what to do?
