Personal loan default

Hi. I have taken personal loan that need to be repaid in 4 years time. I have given 2 years emi in due date but my job was lost and was in deep financial crisis for 1.5 years. I had to take care of my family consisting of 6 members and I am the lone earner of the family. Now I have taken the job but the stability of finances will be taking 2-3 months more. I am constantly in touch with the recovery agents of the bank and told them the whole situation but they are Calling me repeatedly atleast 30times a day not less. I have said to them that I'll pay the whole amount but again in emi options that too after 2 months but will pay the amount whole. But they are not listening to it. I am very frustrated and seems that i'll take my life. The agents have called to my sister's number as I have used her number only once for the conversation with the agent. I have said to them not to call on her number but they paid no heed. I am ready to pay the whole amount but have told the conditions Please help as what can be done. I cannot take this mental pressure for too long.
