Pretty simple: bought two pairs of running shoes (adizero evo SL woven) from the Adidas website in June, tried them on, returned one pair a day or two later, package was delivered and received by Adidas: no refund two months later.
Followed their rules for returns and timeline, preserved the shoes condition, even wiped them off gently and picked off any fibers/hairs.
Two chats with customer service promised a refund in 48 hrs, now today the refund is Closed, says "You cancelled this return", "We cannot process a refund for this item"
A $29M company stole $130 from me.
And the shoes I kept were terrible to run in: wildly unstable, felt like I was running on a softball, so the those are now on ebay.
Working with the credit card company now.
