She send a hi message first To my whatsapp around 7.09 pm. I received an sms Regarding a whatsapp OTP xxx-xxx.

Thereafter she Whatsapp-ed and said that she sent me a six digit code by mistake and if i could give it to her since it is urgent.

I didn't send it back and blocked her from my whatsapp account cos it could be a verification code to access my Whatsapp.
