I'm so sorry for the experience you're having trying to upgrade your account. Does it provide you with an error message? And if so, what is it?
Also I'm sorry if you had trouble getting in contact with our Support staff. It looks like you are an international customer. Were you attempting to call with the international number? This contact page will provide you with our international numbers for support and billing, just in case.
