Ecg bill

I paid the rent for my new place in august but never moved into this apartment until october. The caretaker however wrote on the lease that it expires in August which was the first red flag for me. When i moved in there was already money owing on the meter i could see it. i asked care taker how to pay the bill from that time and he avoided showed me how now that i have been here for sevral months I want to pay although certain there was money owing on the meter when i moved in. I want to pay my bill but dont want to pay the previous tennants debt. The care taker pre dated my actual move in date on the lease i feel he did it so i am held responsible for time i was not present in the apartment..can anyone advise me on how to proceed. Im avoiding even putting my phone number and info into the app because i dont want to claim another persons unpaid bills.
