Blue Cross Health Insurance Reviews

I had 2 claims returned for ambulance bill for a reasons not specified in the policy and only to create more inconvenience and headaches. The first claim was returned because the statement from the hospital was not enough and needed a receipt.The second claim was declined because the receipt from the hospital for ambulance service does not specify origin and destination for the trip like i am going on a vacation. This is the very same receipt the hospital issues to all patients and it is a standard Ontario flat fee for ambulance service, regardless of the origin and destination.
The only reason i am with that insurer is because is a group insurance from the employer. Worst ever customer service!
