Cashe — Harassment by recovery agents

I took a loan from cashe and was unable to pay last EMI due to job loss. Now their tele callers and recovery agents, mostly females are harassing and threatening continuosly using abusive language. Also they should be sued for personal data theft. They sync our contact in phones and start calling and messaging everyone in the contact list saying I'M fraud and so on. Also asking them for money and using abusive vulgar language.
Going to file a complaint against them at nearby cyber crime cell office.
