I wouldn't return faulty items for replacement as you might not get it back. The replacement process for me has involved 8 contacts with different customer service advisers at every point. I was told at first that I would be sent a replacement and that I should return the faulty item. I returned the faulty item and didn't receive anything after 8 days (3-5 day delivery expected). A refund for my purchase was then issued and I was told the item was no longer in stock. I contacted asking why I wasn't told this at the time (as I would've kept the it and made do). After 5 contacts I was finally told that the return/replacement department has a 48 hour delay and that the item must have gone out of stock in that time. I was not given a replacement and since ASOS was the cheapest retailer for this item I had to purchase the same item for much more elsewhere. I lost a significant amount of time dealing with the complaint and ended up spending more money than I wanted. The item in question was from Rains and could've have been replaced under their 12 month warranty has ASOS used it. The item is still in production and it seems that the item is only out of stock because ASOS don't wish to sell it anymore. Unacceptable processes behind the scenes led to an unacceptable outcome and this will likely happen again to other people.
