Why is my house tenant using other peoples credit card to pay his?
You said house tenant and to me that means theyre renting a room. That being the case a house tenant normally doesnt have a water bill so why isnt the water included in the rent? Id presume hes not paying with his own credit card because he cant afford the extra bill (according to his income) or he doesnt have good credit. You didnt say whose credit card hes using, and if the credit card isnt his then are you saying hes paying the water company or you for the water? There are several questions to ask you that you didnt give us answers to.
