Injection site trauma

9 hours after my blood was collected; red mark on the right is from the tape used

I've had it with lab personnel who doesn't know how to take blood samples. This is what usually happens if the person is careless. I had my blood annually checked for cholesterol, triglycerides and the like last Sunday morning. I felt nothing while the person was taking out my blood. I did what I was told to do after taking the sample- put pressure on the injection site, don't rub and don't fold your arm. But the pictures above clearly showed how badly affected my veins were. It has been two days and now my bruise turned purple already. I don't know how long will the bruise last.
