Hello, I have a membership site and all my users paid using credit card when they signed up. Now on renewal some of my clients have paid me before renewal date by offline payments method. Amember system charging all users and amount is deducted from all the users credit cards and accounts. Now i want that only those users will be charged who have not paid by offline payments. Only those users will be charged who have to pay. please tell me how can i do this. I have to refund all users manually and this is not a good practice as most of users are getting angry due to double payments charged. I am using Authorize.net as payment merchant Thanks.
