Regarding the personal loan from bajaj finserv

2 years back i have taken 90000 personal loan from bajaj finserv and from that day every month 2nd was my EMI date and every month i was paying 4191 Rs. in the month of April 2019 i dint make the EMI amount of 4191 because i changed my job in the month of April 19th 2019 and in new company will give salary on 10th of every month . In april end the collection agent called me and asked EMI money to pay i explained my problem and he dint listen my words and immediately he and his friends visited my home and asking money to pay immediately. when i called to that collection guy his words are like threating me and i got scared because of his behaviour. Please help me in this matter how to process further.
