bajaj finance ltd - harassment from collection agent

Since I am at a loss of employment, this month I got late to make my RBL-BFL cc minimum payment. Currently I have landed with a job but my salary will come on the end of month. I have communicated the same with Bajaj FInserv, yet i receive almost ** calls from their collection agent everyday. They get in touch with me on whatsapp. When I told them that it is past *PM you cannot get in touch with me as per RBI guidelines they lose it. I have the whatsapp chat with me. This isnt an isolated incident, previously when I wasnt late on my payment, their collection agents used to call me **rd of every month to cough up the minimum payment even though the due date was *th of next month and i generally make all my payments on the **th of last month due to receipt of salary. One lady told me there was a bounce charge against a PL on me and when I asked her to share the statement, she started calling me names. I got in touch with Bajaj Finserv on email, they called me but no action was taken and now this.
