Reliance Jio Infocomm has spent Billions of Dollars in developing their 4G LTE Platform. However, their Product Managers have forgotten that there are 31 days in some months of a calendar year.

Look at their Detailed Bill Download Interface – It restricts us for 30 Days. So anybody who wants to download DEC-2017 Bill has to query twice which is a pain on the User as well as double penalty on the Jio’s backened server.
This will go in the Computing History as Jio Bill Flaw and will be asked for fresh candidates on how will you design the Billing System.
