No,first contact your caseworker and write them the problem.

Yes, Save all your receipts for work done and parts etc.Deduct it from your rent along w/ copies of said receipts. Enclose ur adjusted monthly rent payment along with a letter stating times, dates Called, msg.s left etc & so forth for said repairs. It would be worth your while to go to ur local currency exchange, bank or even library to have them stamp the letter w/ NOTARY PUBLIC and it's only $1. Good Luck

Yes you can and let your caseworker know they aren’t fixing what’s broken

No you can’t but if you do be sure to be able to produce it when asked if you have it
