About a year ago, I use my name to activate 4 cell phones numbers to help out one of my friend and her family (they don’t have social security number). 6 months ago, she stopped paying her bill. Since everything is under my name I took this responsible and pay off the bill, I can’t let it sit there and ruin my credit. But the worst part is that she was still in contract with that phone company for another 6 months, I end up paying somewhere around $800 for 6 month. (1st bill I paid was for $400, after I lost touch with her I suspended the service, so she can't use it, but I still have to pay for it) if I were to take the whole thing to court, do I have a case? (Lost more faith in humanity after this incident)
