I had $250 left on my WindTab and was gonna switch to a cheaper plan. Their rep offered a $100 promo if I have less than $150 on my WindTab. So I paid $100 to qualify on the spot. Guess what? The next bill came as $250, not only did they lie about the promo, I was penalized for switching the plan! Called the customer service over 10 times and wrote to the headquarters a month ago. All they did so far was to cut my service and forced me to pay. Luckily my contract ends in June. For those who are considering to sign with Wind, you may put up with the horrible signals for saving a few bucks per months, but may end up paying it all back one day if not more. Judging from the comments, I am sure I am not the only one. Never with them again!
