no customer service again

When i was underwritten, i gave the name and practise number of my gp that i wanted to be added as my primary gp. I was advised that this would be done. all this time i have been going to him under the impression that he is covered. Until last month when i submitted 2 claims for him. both declined because i exceeded my out of network visits. So i asked that the call be listened to and i was advised i will get feedback last week. no one has bothered to get back to me. Im so sick if the service i have recieved from your company. The first underwiting error delayed my membership by one month, the second cost me money and now this. Please consider this my 30 days notice to terminate my membership. i am done with your pathetic service
