Would there be any way for me to make this change on a members behalf? Like when they email me to cancel, and I offer them 3 months for $5 and they say yes, how can I just go in and make the change for them? I have had some members successfully log in to fill out the billing modification form, so the 3 months for $5 is listed as a plan in my Stripe account. However, when I tried changing someone manually over to it it just kept billing them at the normal monthly rate of $5 (I think because it saw that they were out of trial). So, how can I make this billing change on a users behalf?
