You cannot place an order with ASOS without providing a valid phone number. A company does this for one reason: your data is a valuable commodity for them to SELL/TRADE TO OTHER COMPANIES. The customer service rep I chatted with regarding this issue says the reason they request a cell number is for delivery issues, but when I requested to handle any such issues via email, (which works fine for other companies), they refused this option. Any company that FORCES YOU to give out your cell number has alternative plans for it--like trading or selling it to. So, by all means, if you don't mind being spammed by every Tom, $#*! and Harry out there, place an online order with ASOS. Deeply disappointed, will never order from them and will warn others away.
