Hi,Today one lady came to our area for selling rexona deodorant we rejected initially and then she asked me to call a toll free number of 1800121170170 and then a message came from Hindustan Unilever and she gets a 8digit code from me,later I was scared whether I got cheated or some scam like going around me.please tell me what is the purpose of that 8 digit code which she received from me.
