The customer service was terrible. We found some cracks on the wall and wrote emails to ask for repairing, but in more than one year time, there are neither any response, or nobody ever answered the phone. Recently we finally got the reception to answer the phone, and said they have forwarded the email to related people. One week pasted nobody called. I called the reception again, saying that we could wait another week. We waited, and not surprisingly, nothing. Can you imagine that you got some cracks on the wall, and in 1.5 years you can't even get somebody to look at that?
