I know about this This is harrasment nd a attempt to hack my device. Last time this happened some classmate of mine did this infront of me just by inserting my number in a website he uses for message bonding , call bombing maybe nd all whatever services the website gave . So this he did it again nd thats enough so i think i am gonna complain the official website of cybercrime with his number now .... Cause it is harrasment nd i am jere trying to study and thus messages keep disturbing and bothering me.
