Unauthorized deduction and fraud service

&lt;p&gt;&lt;b&gt;Location/place&lt;/b&gt;: mysore Karnataka &lt;/p&gt;<p><b>Name of company/service</b>: Tata docomo </p>i have been a victim of Tata docomo’s insincere and fraud service,ever since I’ve been using it.
My previous cases just went by,cause i didn’t have any proof.
But this time its different. i had activated a 3G pack of 90Rs myself using main balance deduction system around two weeks ago. i received a confirmation as an sms showing the data packs validity and usage limit,which was the same which i had requested for.
2 days later when i never got either 3G speed or even the link for that matter,doubt clicked me. On checking my promo pool balance i found that i was shifted to a 2G pack without authorization.
i made a complaint.
At least thats what i thought. After listening to my complain the customers care executive put me on hold with my permission but didn’t put me back.
when i tried reaching the care unit, i found my calls were barred to the executives.
till date problem lies as it was.
they seem least interested into customers interest. but this time things will be different cause i have proof to back me up.
