SCAM BEHIND AIRTEL 3Gb BB UNLIMITED PACKAGE

i want to use this medium to expose the scam of airtel subscription called blackberry unlimited which is there is really nothing unlimited about.
the main issue I'll like to call our attention to is that the 3gb is a virtual amount and not up even up to real 2Gb, if you subscribe to airtel BB unlimited package, by the time you use 1.5gb, your data will be exhausted. Have been observing this abnormality for some time now from friends, colleagues and family who usually express surprise mixed with disappointment when their phones suddenly stopped browsing and on checking their data balance, they're usually met with disappointment of exhausted data balance. but then i was always suspecting something wrong with this similar complain from all these people.
But i too experienced my own after i moved to new environment where the network i usually do 3gb subscription on ( not airtel) have a bit slow browsing problem in that area,
then i was told airtel is a bit better there and based on their advertised claim of being the smart phone network i switched to airtel and subscribed to their 3Gb BB Unlimited package only to realise that the 3gb in real value is just like half ( 1.5gb ) of 3Gb. that is 1.5gb instead of the nominal 3gb..
this deceptive unlimited 3gb got exhausted in less than 10 day. I would have been surprised and confused too if not because of my long experience with data subscription which have been doing since my University days. Apart from using network balance checking codes, i often monitor my data usage by inbuilt phone data usage counter under phone settings which has always been consistent with the like of GLO and MTN that i'm used to...so i wonder why the difference with Airtel, is airtel trying to create another value for Gigabyte other than the one we learn in computer classes. or they are scamming us by attracting us with 3Gb while giving us 1.5Gb,
as far as my study and observation have shown, Airtel 3gb BB Unlimited is far from being close to real 3Gb value, the so called unlimited is a deception, fake and one of their trick to swindle their customers of their hard earned money ( unless airtel have their own version of English dictionary  and definition for Bit and Gigabyte). the screen shots along with this post is some of the evidence of this disservice by the service provide.
