No payment approval

Every time when I take blood test, there is a issue when there is issue when they have to pay the lab, even when you have funds for that. When you call them your call will be transferred to all their call centre agents without any help or promise to call back which will never happen. At times I would be told to tell the lab to send paper claims. There is no one to talk to there should you have any issue or need clarification, your call will be transferred from one agent to the other without any help or clarity
