A dishonest way of doing business
They don't notify you when you spent all of your included credits. They just SILENTLY start charging your credit card when you use up more credits than it's included in the plan. It's not an honest way of doing business. Of course their representative can tell us, "You read the T&S so close your mouth," but practicing this approach, don't be surprised to get 1-star reviews and people spreading the word about your way of doing business. It puts a shadow on everything you do. Like, what else you might do behind the scenes? Maybe hide some valuable keywords from Lite/Standard-plan users in favor of Enterprise users?
