LabCorp review: Lost blood work

Went to Labcorp on Sunrise way in Palm Springs, California. I fasted for 12 hours and they took about 10 vials of blood as my doctor required many tests. After 2 weeks of no results, I went back to the lab to inquire about my results... They have lost the blood and I'm not even in the system as having been there. No apologies, no nothing. How can they lose 10 tubes of blood? How unprofessional and irresponsible. I have to do this all over again, but will never go back to that location. After reading the Google reviews, I see that this place is notorious for losing blood samples. Why isn't anything being done about this?
