Hi,
I have a question about subscription. Let's say I have three types of memberships on my site. One month a user subscribes for a basic membership. After 2 months, he changes his mind and wants to change the type of membership to silver (which costs more money a month). How is this done in alert pay? Does he have to cancel the initial subscription and subscribe again or is it possible to modify the existing subscription somehow?
For example at Paypal it works like this. If a user has existing subscription which has a due payment 15th of month and today's date is 1st of month, user can modify the existing subscription. The initial payment will continue till 15th and on 15th the user will be charget the higher amount.
Can somebody please answer me this?
Thank you.
