Reliance Jio inflates the number of months of validity for its prepaid recharge packs by changing the definition of a month!

So when they boldly write "12 months", you assume a year or 365 days, and you're alright to assume this as a consumer, but in reality it's only 336 days [or a full 29 days less, almost a month less, implying ~11 months], because they've - in small-sized disclaimer print at the bottom - changed the definition of a month! Such nasty tricks go on in the open without bone-breaking fines!
