Tata DoCoMo / Prepaid — Text bundle remove, call back promised but not received

Address:

Dehradun, Uttarakhand

I added a message bundle online on 8/5/2012 which gave 3000 messages for 30 days @Rs 29. But all of a sudden i started getting charged yesterday evening(26/05/12) for the messages i was sending. I thought it might be an error momentarily so stopped after the initial text were sent. Today morning i texted again to check, and i got charged again. When i called customer service they said the bundle has been changed to 1500 messages and also the last message i ever added was on 09/03/12. When i told her that i still have the confirmation text dated 08/05/12 she said she will forward an email to someone and they will look into it and call me withing 4 hours. No-one has called me since then and it has been more than 7 hours.
3 issues now i have with your company:
1. Why a promise of call back not honoured. Is this not unprofessional that your reps promise call backs but they never do?
2. Why your system is not updated about the message bundle pack on my account.
3. In case you changed the bundle in the middle of me using it, it is totally unfair as i was under the impression that i was getting 3000 texts for 30 days as was shown in your website when i added the bundle. You cant just change the bundle while the customer has subscribed for it, its not the way that you advertise one service on net, and change it in between and that too without notification.

PLease revert asap on [protected] which is also the number in question. In case you need the Transaction id : 879123679810000018759169.
