When I worked for a major cable company, the customer database we use is called ACSR. And there is no way to put a customer in a queue and automatically mail out the item when its available. The database is setup like that you can't change it. The customer service rep can lie to you and tell you he/she has submit your request or he could tell you the true and tell you he can't do anything about it.

Of course, what you really should do is ask for the supervisor and then whine about it, the supervisor probably can fire an email to someone who can actually make a difference.

Or the actual solution that works: dump your tablet on ebay and buy a new one; or even the nastier way: fried your tablet with corrupted firmware so you can exchange it. Whining on an internet tablet forum is lol worthy.
