You recharged for 90 days ..
I have done one year recharge On 11th April 2019 I had done BSNL 1699/- plan recharge which Offers 4.2 GB data per day for 365 days .. But now from 1st July I'm getting 2 GB data per day Only.
This is cheating by Bsnl
They have promised 4.2gb data for 1 year but now reduced to 2gb per day
Nobody responded on Twitter .. I have tagged dot , trai, bsnl, telecom minister
Customer care 1503 says we can't do anything .. the plan have changed now.. but my point is I had done recharge 3 months ago at that time I had called cc they told me you'll get 4.2GB per day for one year
