I understand the way you feel as have had the same treatment myself.
Bossini, in the Hyaat Plaza is another shop I am reluctant to go into again, the assistants follow you around the shop at a distance of no more than two steps away, this is quite intimidating and I was put off from shopping there, they did however have a suggestion book on the counter and as well as speaking to the manager of my experience I also made sure I wrote the problem down.
Am shopping again soon and hope the situation no longer exists.
Anyone else had the same treatment??
