Sprint Billing Errors, On purpose?

In my opinion (based on over 8 years of service), Sprint has purposely built in routines on their billing computers that will occasionally create billing errors at random on customer bills- in sprint's favor of course.

It seems to me like they might simply create duplicate call records for some of your frequently called numbers... The really fishy part, is the large amount of calls that I've seen get billed as "daytime" minutes, and that started at say, 6:58pm (though I swear it was after 7:00) - and of course, these calls would rarely ever be less than 45 minutes in duration.

Additionally, I seem to get incorrectly billed for some of my feature packs, pretty much once every 2-3 months.

Having observed these fairly frequent errors with my bills, (never in my favor) - I am lead to the hypothesis that Sprint really is doing this on purpose. In fact, for most of their customers I'd bet an extra $5 or $10 wouldn't even make them look twice at their bill before just going ahead and paying it.

To assume that NO ONE at Sprint has thought of this type of scheme- and even to give them the benefit of the doubt- that *maybe* they aren't doing it on purpose- is in my mind, pushing the limits of naivety...

Recently, I changed to the $100 unlimited plan. (luckily without having to extend my contract). Now, call me old fashioned- but when I sign up for a $100/month phone plan with UNLIMITED EVERYTHING - it better goddamn well cost $100 a month!

Well for the first 2 months, that's not true! Even though I specifically told the representative that I spoke with to start the new plan IMMEDIATELY, instead of waiting for the billing cycle to end- I wound up being charged for Pro-Rated usage of voice and data usage, and my billing cycle was the same as always. To the tune of $75 for pro-rated data usage, totally 2500kb. Yeah, 2500kb. Not even an MP3 worth of data, for $75, along with equally infuriating charges for pro-rated voice minutes.

Now I know of no other situation, no other industry in fact- where having something Pro-rated results in it costing you MORE. It's actually common practice for Sprint to do this bullshit, even with their brand new customers! Instead of starting a customer's billing cycle the day they buy their phone, their billing cycle just about ALWAYS winds up starting like 2-3 weeks later, and their first month of usage being pro-rated.

In fact, if you are a new customer who is required to pay a deposit at the time of activation- and you choose the $100 unlimited plan, about 3 weeks after you activate your phone Sprint will cut off your account because of the "spending limit"!
