What should i do ladies??

Ok so i had my 1st baby at 19. (2014).Decided I didnt want another one signed paperwork to get it done,never happened. K fast foward 2019 I’m pregnant with my 2nd one signed papers again 6/20/19 exact day had my son 2 months early she still didnt tie them. At this point I am now 25 years old. I called the office and explained to someone on the phone she said she dnt see the papers where i signed the 1st time. The reason why she said she probably didnt tie them after my son was maybe because he was born early. Was due in October but he was born in August,I live in Michigan is that any excuse for a ob not to do their job. I also have hydrocephalus (water on the 🧠)and this is another reason why i wanted them tied as well. The lady on the phone told me that i will have to come back into the office sign paper work AGAIN &WAIT 😒. Ladies what should i do im about ready to loose my shit on them i feel this is so unprofessional. I am also in the process of switching ob’s to get a 2nd opinion.
