Worse nightmare

I am out of words, the treatment received from this company is beyond. For over 20 years my father has been with medshield. Last year my mom was hospitalized for an operation. The bill amount due to the hospital was just over 75 000. Only 10 000 was paid medshield to the hospital. To latter start querying codes and ending up with empty promises. A year latter they have not paid the remaining 65 000 due to the hospital however still deduct 6500 every month without fail from my father. To date we still fighting an losing battle, the latest email says the account is stale and new management has over the scheme and therefore not liable for last year's bill.. Medshield is a just a nightmare, the 6500 deduction every month if paid to the hospital from the time of the operation, by now the bill would be paid in full. Every day the hospital calls there's tracing letters but you in the other had don't care, the staff is rude... What kind of treatment are you subjecting to your clients.
