JD - eWAY - Monthly Subscription - how to cancel

Dear,

this is our requirement details.

"On the donation form, it will have a monthly checkbox so if you check it, it will use today’s date as the monthly payment (if it is 29th Feburary, it will use 28th), all the information is stored with eway so we do not need some sort of interface to obtain these information and display them on the site



If I want to cancel the monthly subscription, I will call up the organization and then they will cancel this manually"

I would like to know if it can be achievalbe and how to cancel a monthly subscription in the extension?

Cheers,
Julian
