Liked my job a lot,but got tricked by the recruiter - Foreign Language Teacher English 1 Employee Review

My recruiter blatantly lied to me.She offered me a ¥5,000 bonus upon passing probation and told me,via Skype and email,that it would be in my bank account once approved and that I would be entitled to a free domestic travel voucher anywhere in China.No pay arrived,or travel voucher,and when I told my DoS he was unaware that I was supposed to get benefits.I emailed my recruiter straight away and she insisted on lying,saying that she never offered me these benefits until I sent her back the email clarifying what what she had promised and then she refused to reply to my email.My DoS also emailed his supervisor who insisted on telling me that there was nothing that he could do because it wasn’t stated in my contract.I also raised the point during my exit interview and once again they insisted on only apologizing and didn’t bother to even look deeper into the issue.Kind of strange,right?
