HLI Tree Service Forman very deceptive. Did not finish job nor give receipt Chino California

The problem is with the foreman. did not complete job and give me a receipt . Came to my bed as I am a 72 year old disabled senior citizen and got me to write checks over $2'ooo. Said he would bring me back receipt . He and the crew left and I thought they were going to lunch . Never came back and dug out roots of the tree and trim tree in the back yard . I might take the,  to Small Claims Court and file with The Consumers Affairs Board of the State of California. The foreman also wanted me to write him  &700.00 check  to plant two trees in front yard . I wanted to check with my son first , because he wasn't here . They will not answer phones or return calls.
