Need serious help please

Some guys are texting inappropriate messages nd calling me continuously from different numbers. It's been going on since past few weeks. So, i changed my phone number but as i reached home, my phone started getting same msgs from same number i don't know how... I can't tell my family about this as they are very strict nd naroow minded too...I can't involve police in this as those guys have some political connections nd they had told me very clearly that if i don't do as they say, they will do something i had never thought of....i can't understand what to do so i need help to find a way out as this is affecting my boards preparation very much and it's suffocating too...
