Supervisor Rhonda was extremely rude and hung up on me, even though as I'm quite familiar it will state in your notes that the call ended. I have had very poor service regarding an overbilled issue since October. A credit of over $400 was found by a member of the elite services team. An email was sent out on 1/7 stating that credit would be reflected no later than my January 2014 billing cycle. I've called 3 times in the past week and spoken to 3 different people and told during the first 2 calls I'd receive follow up calls within 48 hours. That never happened and I stil have no resolution. Asked to speak to a manager today, and was told the wait would be 40 minutes but one would call me back. I said that was unacceptable and said I'd wait the 40 minutes. Of course within 5 minutes I was routed to supervisor Rhonda who was extrememely rude from the moment she got on the phone. I asked her to please adjust her tone when speaking to me and was told she had no tone and proceeded to tell me a credit take 1 - 3 billing cycles over and over again and when I asked for her name and said I'd be issuing a complaint she hung up.
