T-Mobile Internet Price Increase - False Advertisement

As was advertised on television and other places, T-Mobile Internet services promised that if you sign up for internet services, the price will be $50.00 a month and will NEVER go up. Well surprise to me! My September bill increased to 55.00 a month without any advanced notice....I understand its just $5.00, but what's the future going to be?.. More raising of the price? T-Mobile, if You're going to make a promise, then keep it. False advertising can get you in a world of hurt.
