Apparently switching is the SOP at this place. I called and made appointment, when I get there she (Sunny) acts surprised, brings me to the room asks for the HF and tells me to wait. I noticed that she had cash on her other hand, then I realized that another person just walked in. A few minutes go by and I decide to leave, so I walk out of the room, she comes over and I ask for my money back. Another lady (I don't know who it was) insist that I stay but cannot tell me how long I have to wait. I said that I prefer to come back when they are not busy. At this point she raised her voice, that was not cool, so I just smiled and asked for my money back again. Needless to say I am not planning to go back after this experience.
