No response to e-mails

I called a couple of times to cancel my upgrade, but yet, once again had to experience the frustration of being sent from pillar to post by consultants. I sent an e-mail & the automatic response said that I will get a response \within 24 hours\". To date I received no response via e-mail or via phone. I want to cancel my upgrade & I was doing it within your window period so it CAN'T be too late to cancel because you DONT want to help me. I WANT THE MANAGER OF THE CANCELLATIONS /\"3CD' DEPARTMENT TO PHONE ME!! "
