1 year worth of gas bill

[Maxim K.]

Hello,

I have a situation where my tenant ( Joe ) moved into apartment (A) 2 years ago, previous tenant from that apartment ( Christina ) moved out of that apartment (A) to my another apartment (B) , now Christina was supposed to cut off gas for apartment A and only keep Gas for apartment B . She ended up keeping both and kept paying for both apartments Gas bills

Question , is there any way to charge Tenant Joe gas bills for the last 2 years which is around 1100$

Joe new, he had to pay for gas and electricity . But never said anything

Christina is relative. So I would love to help as much as I can

thank you
