What else would prefer them say? That there is some old guy in back feverishly working his slide rule? Of course it's done automatically by a computer and there would be no reason for them to explain the inner workings of it to those at the call center.
My point, which you have failed to grasp, is that they can't explain their policy, because their policy, by its very design, is to force users to a tiered plan. It's not "throttling heavy users." It's a way to clear their books of the contracts they advertised to get people to join their service. The truth of the policy is "we're throttling as many users as we think we can get away with to get them to switch." Of course they can't say this.
It seems very obvious that, yes, you'll both be throttled. You would be the instant you pass the threshold and they would be as soon as they do.
Since throttling isn't lifted until the end of the billing period it's possible (however unlikely) that if everyone were to go over their threshold they could, in essence, throttle all unlimited user speed at once.
Yes, which makes their "top 5%" argument a complete fallacy. As you point out, they could throttle every single user of their unlimited plan. The "top 5%" DOES not equal "100%" to any rational mind.
You know what's even more hilarious and something that they find funny? You continuing to pay them each month while complaining.
Well, their call volume goes up whenever I call, which makes their employees work harder, which either a) prompts them to bring on more call center reps, costing them more money or b) prompts employees to quit, degrading the level of person willing to work for them. I also mentioned that I'll be leaving them as soon as I can not be paying them for an early termination fee, and canceling other services with them as well. I'll also be telling friends and family of my experience, and advising them of how AT&T does business, hopefully costing them future customers. I guess it's funny that they get a couple hundred dollars from me for 6 months, and then lose far, far more down the road. Yep, a laugh riot.
I hope you work for AT&T. If not, you're simply a corporate apologist or "fan" of a company that has no such allegiance to you. Anyway, feel free to ignore any of my future "complaints," as I will be doing the same to any of your responses.
