Reliance Communications — I was cheated during 4g upgrade

Address:

560066

I was using rs.999 - data 40gb plan
I was told after 4g upgrade plan will remain same.
After i spent money on buying 4g device and migrated to 4g.
My plan was changed to rs.900 - data 5gb.
And on top of that, they have disconnected my services now when i consumed 6gb as reliance people say i have to pay first rs.1700 then only they will resume services.

This is fraud totally.
Ambani is just filling his pockets with all this duped money.
