I can say the outlander pack will work as you would know if you have ever used It , so you would get 60 days , 1050 cartel coins and the pet
all that is left is the 30 day retail code here but if this has ever been applied previously, the code will fail as it can only be applied once per account as well. so if you bought this or say a retail box before then you will be needing to approach origin for a refund as the code wont work when you try to apply it.
All you can try is creating another paypal account , try another credit card (preferably mastercard not visa ) (EA hate visa debit cards)
edit - try loading money onto the paypal account and use that and not a linked card
other then that you could try to phone them but I doubt they will know how to sort this error and just say wait longer
