So, my girlfriend got into a single vehicle accident last year & in the process she hit a power line pole. This was almost a year ago but recently she received a bill from Oncor for the broken power line post for fixing & replacement & it's about $2k.
My question is does anyone have experience in this situation? I'm wondering if she doesn't pay it will they try to sue or will it go to collections & then we can settle for a lesser amount? I know their a big company so I'm worried about a small claims lawsuit, but hoping that it will go to collections & we can settle for a smaller amount.
Any guidance would be greatly appreciated.
Happy 4th!
