i have a little dilemma
basically my flat mate let her boyfriend stay at our place for a couple of months over the summer as long as he paid for the electric/gas/water/phone bills that he used. so he owes me 70 odd quid because all the utility bills are in my name. they have now split up and my flat mate basically thinks that it isnt her problem anymore, and said ex boyfriend isnt answering his phone, blocked me on facebook and i have no new address for him.
am i right in thinking that i dont really have a leg to stand on if they dont pay me?
or is there someone official i can talk to?
