Surprise, surprise. The specialist never contacted me within 96 hours. I had them call me again. (P.S. if you call in the mornings, there is no wait time.) By the way this removes you from the list of your case number to be reviewed by a specialist when you reopen your case. That's really stupid. At this point, I'd been struggling with the issue for 7 days and I just asked for a return. Good luck @Hnnadii getting a response.
They tried fixing it for me on the phone one more time, and the EA consultant said that her and her manager tried inputting new codes, and none of them would take. I will say everyone I spoke to was very friendly and wanted to help me, but they just couldn't figure out what was wrong. If you look at some other forums on this issue, it has been happening since 2013. They need to fix their site. It's ridiculous for us as consumers to pay them money for a product and not receive it. I don't think that I will be buying any more EA products, as much as I love the Sims. Partially because I am upset and also because they said if I tried to buy another product from them there would be a good chance that this problem would keep happening and I would have to refer back to my previous case number if an issue arose.
And you know if I don't receive my refund credited back on my bank account within the 5-10 days they said it would, I'm going to call EA even more angry. Luckily, they at least sent me a confirmation email saying that my refund had been issued.
Good luck to everyone who is having this issue. Hopefully someone notices these forums and starts responding to people.
