Wrong billing 3 months in a row

<p>We moved in on June this year, 1st statement had a brought forward amount of which when we asked the caretaker he said he doesn't know. Then we reported the broken or damaged things that we found to the caretaker we were told the people from afhco will come and fix it only for those damages to be billed on us yet the caretakers book showed that he reported the matter before we even moved in. We queried why he said he is fixing it, however today again the same amount charged for the broken window is brought forward as if we are responsible for it. Again this damages are affecting our credit score because it is seen as arrears. We can not pay for any damages caused before moving in to this flat. Reference number 34782</p>
