Poor administration and ITC record affected

Where do I begin, My wife's account shows zero balance, yet they have handed her over to ITC. When I contacted them they also see zero balance on their side and will have the issues resolved. Almost 12 months down the line and I am still awaiting a response them.Even after sending numerous e-mails to them they refuse to get back to you.When you call them they transfer you from one person to the other or cut the line on you. I had to send POP to more than one person and yet they could not help you. They make empty promises and now my wife gets call from ITC due to their incompetence. They said it would take 21 days to have it resolved. These are the most *********** bunch of people that I have ever come across when dealing with customers and resolving issues.
