[Resolved]  Nobroker — misuse of my number, misconduct and violation of privacy

My name is pooja and i reside in mumbai. I hired a relationship manager named chethan mallu through nobroker for a period of 45 days to help me find a house to shift in. My package expired a month ago and since the last two days, i am getting unsolicited whatsapp messages from my previous relationship manager through his own personal contact number wanting to be "friends" and urging me to reply to his messages over and over again. After telling him that sending such messages are a clear misuse of my number, he replied with "not at all if you permit me". This is very appalling, downright disrespectful and is a violation of my privacy. I appeal to the authorities that they take note of this and take strict action against mr. Chethan mallu.
Attached are the screenshots of the whatsapp chat.
