Extreme disspointment

My Wife is due to give birth this Friday and you guys are giving us the run around with a pre auth number, no one knows what's going on, they are sending us from department to department, giving us excuses that the gynae office was asking for preauthorization after hours, which we don't understand, and this has been going on for weeks. The waiting periods were discussed, and you guys debited a few months period in one go saying from Aug the birth will be covered, now you are giving us stories to pay cash and we will be reimbursed, who has 80k cash especially if you guys confirmed we are covered, and we didn't even have time to save anything. No one is calling back my pregnant wife is calling in every hour and we are being given the run around, truly disappointed with the service and amount of stress we are being put through.
