Worst experience!!!

In June I began cancelling my old line to move the line to my new address in August. One would think that's sufficient time for Vox to arrange everything? When I moved to my new address I was still being billed and debited for TWO addresses. I thought it was the penalty fee (for moving within 12months). I then discovered it was a double debit. Ive been communicating with Joanne and Brett (who is supposed to be her superior but hasn't responded even once) and I'm still getting threat's from accounts wanting to suspend my account. I'm beyond furious and disappointed! Joanne keeps saying they are sorting it out, and making payment arrangements for the penalty fee, but to date nothing has transpired. I'm still getting threatening emails from accounts. I've been a loyal customer for year's and this is the worst experience I've had with them.
