Dear sir, A lady came to me and said that she sells domex bathroom cleaner and she needs to make a call. Then have given missed call through my phone on 18001211563. Immediately a message with unique code was received on my phone. She wrote down that number and went. I doubted that and immediately I ran to her and asked about the same. She said that nothing is wrong and it is just their company activity.

I need your help in knowing whether it is any fraud related..
