I had a store approval with Selfridges on 12th Wednesday this month.
It ought to be at 11:00 am, however, after being waited for extra 40 minutes, finally a confused lady appeared and ended all in rush. They even didn't check my ID either. They seemed to have no idea who was going to interview me. In order to arrive to Selfridges Staff Entrance in time, I called and asked them how to get there, Unbelievably, the staff didn't know and told me to search on Google. What a useful suggestion!
I don't mind spending time on them but I do mind their careless style and negligent attitude which does not match their marked luxury brand at all.
