This is my 10th year with internode and it is a shame to say that I will have to move. I have spoken to over 5 different reps over the course of 3 months to get a simple incorrect double charge fixed, as I recently move homes, and it is still not resolved. The final straw was checking in on progress today only to have the support lady hang up on me. When I called back I spoke to a lovely guy who informed me again to wait for a call back within 24 hours.... this is getting beyond ridiculous. It is clear on the records when the site visit for setup was, so why am i getting charged for a period prior when I wasn't there??

EDIT: thanks for your reply. The last ticket number I have is 21203816. I don't have the no. from last friday but I spoke to a lady named Lysandra.
