Have to pay over 1000eur for IUDs that did not work!! Different doctors told me that I didn't have to pay for the second and third IUDs after the previous ones did not work (despite their measurements and recommendations), encouraged me to go through the uncomfortable procedures, only afterwards to have the hospital bill me for things I was told I didn't have to pay. When I told them what the doctors told me, they said that those doctors have left the hospital. This is just ridiculous and very unfair!! I feel robbed. Nobody takes accountability in this hospital.
