Unhappy with service

Good morning, I went for test in April to possibly join an life insurance. For some reason the invoice was made out to me and not the insurance. I have been struggling for speaking to people at Ampath that has either said the will not change the name to the insurance to someone that said the will make the necessary changes but never did.

I am not able to make the payment, not even on down payments and while the insurance says they will pay for the test I really just want the invoice name changed.

Why must it be so impossible to make the change?
