Glocell's shocking customer service

<p>I am unable to reach anyone at Glocell who is able to sort out an invoicing problem on my account. I have written numerous emails requesting someone to contact me. Apparently my problem has been escalated, but I have no idea how high this has to be escalated as it's been months now with no response.</p> <p>I have recently signed a new cell phone contract with Glocell and I'm bitterly disappointed in their service so far.</p>
