THE Unexplained Telephone call

Welcome back Readers :) hope you are having a good time. This is the another episode of unexplainable activities happening around us. Let's start the story

My father stayed at his friend's house one night because of work. The next morning he wanted to check on us. he dialled our telephone number. Some guy picked it up. He said things like shame on you jagat. How could you stay at someone else's house knowing that your wife and your daughters are alone at home. HAVE YOU LOST YOUR MIND? YOU ARE A FATHER OF TWO, STOP BEING SO STUPID AND COME HOME. The guy kept on saying such things. My father didn't understand what just happened.  He asked him his name but the phone got cut. My father thought it could be one of his family members visiting our home. That's the only thing he could think of.  He called the lady living on second floor to check on us(We lived on the third floor). so she climbed all the stairs only to see there was nobody at home. Yes,the house was locked. My mother and I were at my sister's school paying her fees. NOBODY was at home that time. 

Even if we assume my father called a different number, it does not make any sense. I mean come on he knew my father's name. He knew he has two daughters. He knew our family. STILL at this date,we don't know who that guy was.  My father says it was his big brother.he is the only one who would scold him like that(my father's big brother died 3-4 months before the telephone incident).

PS: This actually happened. I am not making up stories guys.
