Spent over 2 hours on the phone trying to resolve a billing issue for my mother, a 20 year verizon customer. Spoke with 3 seperate agents, the second said we would be transferred to a supervisor. Ended up holding for another 20 minutes just to get connected to someone who wasn't a supervisor. Got placed on hold again, then at 2 hours and 14 minutes into the call, the agent takes me off hold and I hear loud voices as if she is out at a basketball game or at a party. I call her name and no response. After several minutes of this, she disconnected the call. Having worked in a call center, hanging up on your customers is unacceptable. Verizon, I'm disappointed. You are too expensive to not have top notch service.
