Data expiration, congestion and overloading

Correct me if I am wrong but my view is that the whole data expiration issue is a misleading lie at the side of the operators.

“The reason for data expiration is that we purchase capacity on data ‘pipes’ from other providers and this approach helps us to understand how much capacity we need. If we over-provide capacity and it’s not used, then that data is in effect lost and can’t be resold at a later date. This impacts our costs and our ability to continue to bring data costs down."

1) Data expiration provides almost useless statistical data compared to real customer and system data.

2) Data expiration don't bring prices down and actually increase the price of data.

a) Do network operators ALSO buy data pipes on a hourly, daily or weekly base?

b) Can network operators show proof that they use data expiration in their calculations?

c) If poor statistical data like data expiration dates are so important to ensure a sufficient and stable service, then why are REAL customer and system statistics ignored and there are so much congestion and overloading of infrastructure?

With accurate real customer, system and usage data it's actually stupid to include data expiration in purchase calculations because it's definitively not done hourly and there is no way to know when a month or longer bundle will be used. (so if I buy a 10 million GB bundle on the 7th in May WHEN will they purchase a 10 million GB data 'pipe", May or June or both and yearly bundles?)

That data expiration bring prices down is misleading because the most likely scenario is that data expiration statistics is only used to make more money from the poor as per the following illustration.

Monthly data purchase versus utilization = 100%
Daily data purchase versus utilization = 50% (so 100% paid for but 50% less cost)

So with such statistics, they can offer daily data bundles at 40% "less" and make actually 10% MORE profit.

Or from other perspective the "lower data prices" that data expiration enable as they claims, should be calculated with ACTUAL DATA USED (thus minus the expired data) and the amount paid for it.

If 1 million GB daily data is purchased at say R1 million rand but their REAL statistics show an average of 500 000 GB utilization, sure a hell only an idiot will buy 1 million GB data and instead buy maybe only 500 000 gb data and pocket the paid for but not purchased (expired) data as clean profit, so the customer actually pay MORE for LESS.

At the moment my speed tests show a 20.97MB/s download speed at 2am but during the day the speed tests can only reach 1MB/s or even less and that CLEARLY indicate congestion and overloading like hell, REGARLESS even Vodacom's own real customer and system statistics so the change is zero, nul, bokkerol that "data expiration" had or will ever make any difference in purchase or infrastructure decisions.

Above, congestion, overloading and slow speeds due to under-provisioning blow the argument that data expiration is necessary to prevent under-provisioning into pieces.
