So I had the pop up again and naturally tried to buy it again since I thought it was a great deal. Instead it gave me 2800 crystals. Not even the 3500 from the shop for the same price. I dealt with 4 different customer support people and the last one was the only guy to be somewhat helpful. He forwarded it on to an in-game specialist who will take "at least 3 days to check it out". It's a bit frustrating.
Thankfully Apple works much faster than that and just refunded me.
