To those that are waiting--in my opinion, I don't think calling helps all that much unless you are lucky enough to get a Tier 2 person that is actually willing to do some work and help you (which has been a rare occasion for a few people on here). Save yourself the headache of dealing with incompetent people and instead send emails and requests through their system all at once like I mentioned above to Jimx91. Just my two cents based on observations throughout the forum and my own personal experience.
