ASOS have a Customer Happiness Grade of D. Customers are unhappy with their refunds.
Whenever I return an item and request a different size instead of a refund, I always get a refund instead. This needs to be sorted.
I recently purchased plus size active wear from ASOS the products arrived earlier than specified which was a pleasant surprise. 2 of the items fit and another 2 did not. The return and refund were processed quickly.
