[Resolved]  Tata Docomo — Wrong charges on postpaid rental

Address:

Pune, Maharashtra

Hi Pahredar, This is my first communication with you. I want your help on the issue i am facing.
I purchased a Tata Docomo Postpaid number with 899/- plan with 850 security deposit around July 2012. I was paying bills on time.
Number [protected] , Name- Amit Kumar Soni, Pune(Maharashtra)
Plan – 899+49(SMS)+49(Data)
In the November end I got some work out of Maharashtra and I requested Tata Docomo Customer care over mail and over phone to change my plan to 149/- per month on 26 Nov 2012 and remove SMS and Data pack. They promised that it will be effective from 1-dec-2012.
I paid bill of 3200/- for December month and when I realized I lodged a complaint with Tata Docomo on 15-Jan-2013 that you have charged me with wrong plan. They promised me to return me the amount. But when no action taken till 10-Feb-2013, I called them to close all services to my number and tell me the final amount pending. They have sent me a mail asking to pay 16519/- as final amount.
Amount which should be returned to me is:
Plan charged to me (fixed rental)= 1117+ 560=1677/-
Dec 2012 899+49+49+120(ST)
Jan 2013(till 15 Jan) 450+25+25+60(ST)
+security deposit of 850 is with Tata Docomo.
Actual should have been charged (fixed rental)=167+84=251
Dec 2012 149+18
Jan 2013 75+9

Kindly help me.
