Microcare Diagnostics private limited death of my mother due to fake lab reports thrice

My mother had a heart surgery on 4 MAR. We called Microcare for PT-INR test for her. They reported blood to be thick. We increased her warfarin dose as blood was required to be in 2-3 INR range & lab reported 1.2. They gave fake reports thrice due to which she had internal bleeding & then she died on 16 MAY.
