StashFin — Emi failed

I have taken a loan from Stashfin where I have made my 1st emi clear but as i lost my job now and i had spoke to customer representative regarding this i have asked for a time from them but now they sended my case file to collection department.I will require few months time to go ahead and repay it.And what a worse customer support there is no option to contact them only they can contact us.If we do email they never give any solutions
