Will CHI cancel my visa?

I have J1 visa. I came in America,there were no work for me. I was spending money,now I have to pay for housing for 3 weeks. I am getting money at my employer just to pay food and housing fr 1 week. CHI sent me email that we had to get with us 800 dollars and now we have to ask our family members to pay the rent online. If we will not do it in 24 hours CHI will cancel our visas. What to do?
