Upgraded and got no response or update.

I upgraded 3 weeks ago and no one ever got back to me. I had to go in a week later to find out whats going on and got told that there's no stock, but no one let me know. I contacted the facebook page to ask for assistance and was told they will have their mobile team contact me, I am still waiting. NO one calls to update me. I am not an unreasonable person so if they let me know every week whats going on I wouldn't have had a problem but they told me it will take 24-48 hrs and its well over the time. when I tried to call no one either picks up or the mailbox is full so in actual fact there is no way of getting a hold of anyone. I went on the website to send an email and the thing keeps refreshing and it does this when I try to chat with an agent. poor service really and it is really frustrating. I want to cancel my upgrade but there is no one to assist. I am so disappointed.
