Complaint against TATA DOCOMO for providing less GPRS data on Recharge of RC95

Location/place: Indore, Madhya Pradesh

Name of company/service: TATA DOCOMO

Dear Sir/Madam,

On 11th JUNE, 2012 night at 10:20 PM, I used TATA DOCOMO service Number *191# to recharge GPRS PACK 95 on my mobile and after the recharge I received message that:-
“STV Recharge Successful.MRP: Rs. 95, Validity: 30 days, 4 GB Data. Not applicable for [url=http://www.vuclip.com]Vuclip web video search[/url]. Standard data charges apply. Tranc ID:138593504.”
But when I checked my GPRS Balance it was 2048.00 MB (i.e. 2 GB) instead of 4196.00 MB (i.e. 4 GB). So, I called to customer care for the same query but I got reply that company has changed its data tariffs and you will get 2 GB only, also now onward you will get 4 GB data on recharge of RC98.
I replied that neither you gave prior intimation that your tariff changed nor RC98 is updated in *191# and if your data is reduced to 2 GB then why you replied in your message that your account is updated with 4 GB. But after few discussions call was disconnected by customer care employee. Then, I used my second number for the same query as after one call to customer care I have to wait 24 hours so that I can contact with them again, but when I called them that time they rejected to lodge my complaint.
Then I mailed my query to TATA DOCOMO customer care email id i.e. [email][email protected][/email], that time I got automated computer generated response that:-
Hi,

But, after waiting for 2 days I got no reply from their side. Then, I forwarded my query to TATA DOCOMO Appellate Officer Mr. Deepak Sethi on there e-mail(i.e. [email][email protected][/email]), from there side I got automated computer generated response that:-

Also, after few hours I received one call from one of their representative and she asked that “are you sure, that you received the same message as you forwarded?” I replied, “YES MA’AM, I received the same message that your account is recharged with 4 GB data but I got only 2 GB data. So, she told me that, “okay we will provide solution to your query within 48 hours”. I said ” okay, thank you”. But, after completing 48 hours I received no such call or message or email from their side. Then once again I forwarded my query to the TATA DOCOMO Appellate Officer that I received no positive feedback from your side then again I received one automated computer generated response that:-

Hi,
Thank you for writing to us.
We have received your mail and shall respond to your concern within 2 working days.

Then, on 18th JUNE, 2012 one of their employee called me and told me that on 19th JUNE, 2012 we will update your GPRS Balance with 2 GB. But, nothing such happened and again I mailed to them with same query and once again I got one automated computer generated response that:-
