Reliance Jio Infocomm — data stealing

Address:

Ahmedabad, Gujarat, 380019

Dear sir
I'm using jio services for my m # [protected] for calling and net. Right in the morning i get up and i receive a msg that 50% of my 1.5 gb data has been exhausted. This is nonsensical and ridiculous. No one else can use my data.
Also jio doesn't give facilities to talk to its representative. Please take necessary action so that we can talk directly with a jio personal.
Thanks.
