Frustrating

I am at my wits end with this service provider. Me and my healthcare provider have spent an exorbitant amount of time calling and following up on a few claim. For the past two months we have been frustrated with conflicting information, incorrectly logged claim codes and a complete lack of follow up of any kind after literally begging for assistance. The head office in Century City told me only the call centre can help after waiting for them to help me for an hour and the call centre people are not allowed to e-mail me directly and there is no way i can follow up on my issues. Every time I call I have to explain the issue over again and nobody follows up. Everyone is friendly but nobody can actually do anything helpful. Their service leaves me with the impression that they are trying to wear me out and frustrate me until I give up. Think twice before using their service.
