Paying for the mistakes and delays made by Ampaths Account Departments

I went to go do a full blood test in January. The claim was submitted as advised by my medical aid a week later however the used the incorrect ICD Code. They came back with the correct one in April. By then my medical savings had been used up! Today, I am told that my account has been handed over to debt collectors and I don't know why. Someone made a mistake and I am paying for it. WOW!
