Student visa JW202 charged $1550 BY agent in China

Hi, my daughter received an admission notice from a Chinese agent that she has been admitted to a named university. the same agent has now charged us $1550 in order to process a JW202 visa which they said has to be processed in Beijing but we have not received an admission letter from the same university. does such charges of $1550 exist and are they truly processed from Beijing? please advise. thanks.
