If I were you, I would contact the landlord, both verbally and in writing (send it certified in case you have to go to court) stating you disagree with the charges. You can ask the debt collectors to stop calling, and say you prefer to deal with the issue through the landlord directly or through a lawyer.
Bake chicken breasts, uncovered, for 18 to 20 minutes or until no longer pink (use a meat thermometer to confirm that the chicken is heated through to 170 degrees F). To store: Let chicken stand for 30 minutes to cool.
You should bake 2 lbs. of chicken breasts in the oven at 350  degrees for one hour if the chicken is on the bone. If the chicken  is boneless it will take less time. generally bake mine at 350 degrees for 35-40 minutes and then cut at the thickest point to see if the juices run clear. If you bake too long it becomes too dry. I always bake my thawed chicken breasts at 375 degrees for 50 min. and they come out juicy and fully cooked. The juices need to run clear.
