Waiting over a year

So.... I have been waiting for over a year for someone in management to contact me regarding my account. Since September/October 2013 i have been over-billed. I have sent tons of emails asking for someone to call me because every time I phone customer care, I get cut off and no one calls me back. I posted a comment on Hello Peter a year ago about the same issue and I got a response that they have tried to get hold of me... which was a lie. Due to this lie, I sent them an email with a number and time that they can contact me on. Due to my career, I can not take calls at any time of day. And still nothing. So this is the last time that I will be asking Virgin Mobile to please contact me so that i can stop having sleepless nights over their incompetency.
