Hello, coach. I would like to inquire about something. I purchased the 199 course. I have already sent the payment screenshot to customer service. Is it because I entered the wrong place? In the live streaming course, the coach can't see the messages I sent, and there's no way to speak through the microphone.Could you please tell me how to connect the microphone in order in xiao e tong? Also, how do I make an appointment for a one-on-one lesson on Monday and Tuesday? the coach promise that if we buy the 199course we have opportunity to communicate with coach one to one, but I can't find the one to one course open to me
