Received an Exclusive Offer on Lovestruck Pack, did not receive discount

Hello! I received an email stating I had a personal coupon for purchasing The Sims 4 Lovestruck Expansion Pack! The email stated "Your discount will be applied automatically!" I clicked the "Learn More" button on the email, which took me to the official EA website.
The website states "This coupon is only available to players who got an email from us letting them know they have an exclusive offer for 'The Sims 4 Lovestruck Expansion Pack', then how to claim the special offer. However, after following the instructions, I was still charged full price plus tax for the Lovestruck Expansion, and since there was no stated code or discount percentage, EA Support can't refund my purchase :(
