Reliance Infocomm — Ly[censored]nlimited data offer shifted to 4gb per day cap

My no. is [protected], i purchased lyf handset with free jio sim which was activated around 20th aug'16.
I used the unlimited uninterrupted data service for about 8 days only as i had to move to a location where jio services were unavailable.
Now after returning back to my home i see that the speed which earlier used to be around 1.5 to 2 mbps has been reduced to 200 kbps and on top of that most of the sites doesnt open.
Now to my biggest surprise jio has put a cap of 4 gb data usage per day and 128kbps speed after consumption of 4gb per day (which is actually equivalent to stone age internet service of dial up speed where nothing ever opens, not even myjio app on lyf handset itself).
The promise of free unlimited 4g internet without any data cap per day was the only thing which made me and many more like me to buy the useless handset of lyf.
This is unacceptable and is huge cheating on behalf of reliance jio.

I want my services to be moved back to unlimited 4g internet without any cap asap.
