Very disappointed client

Still to date with nemours emails sent to escalate and to flexicarediscovery email address I've had no response from anyone besides a call from Hippo. I have canceled my debit order and my membership and refuse any monies to go off my account due to the bill not paid in full told to Dr's rooms they never received claim dont accept accounts after 4 months ,but the bill was partially paid when I try query this with them I get no response from Flexicare.
