Please help my terminally ill sister

In April of this year, my sister April Matthews went to the ER since she had a lot of pain in her abdomen and could not keep anything down. After several tests, she was diagnosed with stage 4 colon cancer; it is terminal. She had applied for a redetermination of disability close to 2 years ago; she was still waiting. Once I found out she was terminal, I called the social security office in April, and they agreed to expedite her claim. Social Security called three weeks ago. They called to tell her she was approved for disability. She has not received any benefits; when she reaches the Social Security office, no one can tell her anything. They agree to have someone call back, but they do not call back. I am asking if anyone can help with paying her next couple of months' rent and things she needs such as toiletries, cat litter, soap for both laundry and dishes, etc. Her rent for July was due on July 1st, and I am afraid she will get evicted; this is the last thing she needs to worry about.
