Worst company to deal with

After them listening to the voice recording and proving that I'm right, I have to now prove that I've been billed incorrectly!!!!! I mean seriously. I also did my own investigation, and was mislead with false information. Now, trying to get a team leader to phone me!!!! Their constant response, well escalate the problem!!!! Only for me to call back every second day. On hello Peter, they apologist for all to see, but the public don't see the incompatance one has to deal with!!!!!
