Yep! You guessed it, one star so I could write this review. Regardless of how the app works Asos itself is ludicrous. I have received the incorrect size twice and then told the issue had been passed onto a "specialist" whom i never heard from and was informed they were very busy. I must say it is not very reassuring that a company/outlet needs specialist in such a "busy" area of the business. They were very prompt in taking payment,5 stars there. The word refund resulting in deafening silence
