In real life, when you don't like a product or business and the customer service they provide, you stop using said product or business. If enough people feel the way you do and stop using their website, I'm sure they would change their ways and implement better services to accommodate you.
Having that said, 11 is a bit young but this is the internet. There really is no sure way of checking someone's age. Heck, Butane was only 12 when he rised to power. He was still in middle school playing with yo-yos and watching Wizards of Waverly Place after school with Beef. Who are we to judge?
