Jedi Temple Loot crate (Customer service unable to verify Promocode: JEDITEMPLE)

EDIT: EA refunded the money for the pack, I appreciate the help MeatHead 👍

've personally had a horrible experience today.
I had filled in the promo JEDITEMPLE and at checkout it said 0 euro. 
After completing the purchase I was still charged the full amount.

I've already had a full discussion with the EA customer service, I was first connected to 1 person (live chat) and transfered to another who apperently specialzes in it.

This is what Customer service said:

"We are sorry but the team can not validate the promocode, we can not help you further."

I've had a conversation for over an hour, had to explain multiple times that the promo code was lituarlly on the offer itself "jedi temple guard loot crate" inside the official Swgoh webstore and yet they werent able to validate it???

This is extremely scammy and I would like to request a refund. As a student I don't have the money to spend on these kind of bundles and thus only purchased it because the promo code claimed the product would be free. 
This im pretty sure goes against the European Laws.

Below you can see an image taken directly from the store and the offer. 
During the customer serice I wasn't even allowed to share the attachment.
Overal this is just once again a very scammy move from capital games, should have just made the product free to avoid these kind of problems.
And this was not even me forgetting to add the promo code, I ADDED IT and was still charged the full amount....
