Hello, I am using a recurring billing scheme with EFSNet payment processor. Initial signups work fine, but when Amember goes to re-bill a month later they are failing because of a "Duplicate Reference Number". Or Amember is using the same reference number to bill and the CC Payment Processor is denying transactions. Any ideas no how to fix this?
Ok....just an update, I found out why this is happening, it's NOT Amember, it's the processor EFSNet They have a security feature that will not allow the same dollar amount transaction to occur more then every 20 times. SO basically you have to fax their Data ENtry department and have it turned off. All in all EFSnet's support is very good. I recommend this payment processor
