Cleaning lady living in a van

"I saw a movie on Tubi last night that I cannot find anymore. The plot is about a woman, late 20’s or early 30’s, white female, who lives in her van that is broken down, and runs a cleaning company. It opens with her going to an office with papers all over the floor, and she’s dancing to “surfer rock” (according to the captions) while vacuuming the floor. She visits her mom, who is cold to her. Then she retires to her van, where she tries to reach someone on her HAM radio, but fails.

She naps, then receives a mystery phone call asking her to turn off the electricity to his building and he wires her $500. She goes and does the job, and the building catches on fire.

Then he contacts her by a messenger app, and requests she go to a house and steal something. She steals a photograph.

I began to fall asleep here. I recall that she meets her mystery employer, a sick man who is in his sick bed."
