Cashe — Harassment

I took loan from cashe app and I was paying the EMI without fail till April, but due to some unforeseen circumstances, I couldn't able to do the payment for the past 2 months, because of this they are harassing me over the phone and threatening me tat they will come to my home for collecting the payment. I'm really feeling very bad as I'm a single mother, I requested for some time to do the payment. But they aren't ready n harassing me frequently. Kindly please help me so tat I can peacefully do the payment mostly by next month end with out any delay.
