Hello, I'd like to know if it's possible for Uppsala Länstrafiken (UL) to charge a fine they gave me when all the information they collected from me was my phone number and my name. They do not have my personal number. I do not have a swedish ID card but I do have a swedish number. I was not aware I needed two tickets for a trip considering I have a monthly pass for SL. Now I'm wondering if I should appeal this ticket or if they can even charge me somehow. In the "personnummer" section they wrote my birthday. I feel like if I appeal I will provide them the information they're missing. Thank you for the guidance
