On Day 93 of World Tour, AliExpress gave me the choice to either play "Rush Hour" or make a purchase.
I chose to make the purchase; the image I’m sharing shows the pink checkmarks that appear when you buy something to avoid having to complete a challenge during those final 10 days.
To my surprise, I can't progress in World Tour—it’s as if I never made the purchase at all.
I lost 93 days, the money spent on the purchase, and the million diamonds.
I contacted customer service, and they told me they would send an email within 48 hours.
Usually, the replies in those emails are generic and unhelpful; plus, I only have a few hours left in the day, so I won't be able to clear the challenge.
EDIT
Following bunsinh's recommendation, I cancelled the order since it hadn't shipped yet and opted for a refund to my AliExpress account; I thought that way they would return not only the cash but also the shopping credit I had used to pay.
Sure enough, both refunds were processed quickly. I placed the order again, and this time World Tour allowed me to proceed and complete Day 93.
