I recharged Rs 123 Rate cutter by this (03.01.2013) evening around 6.30 PM through Online facility (Official Tata Docomo Online Recharge Website).
The website indicated that, "Local On-Net mobile calls free from 10pm to 6pm and 1p/6 sec from 6pm to 10pm. Validity : 30 Days", for my recharged rate cutter Rs 123 in Tamilnadu Circle.
But, I was deducted as 1p/3sec (20p/min instead of 10p/min), for Tata Docomo calls during 6PM to 10 PM.
I called the customer care representative through 198 complaint tollfree and raised my issue to him, but he (Mr.Gobi) was not respond to me properly and he cut my call without any notification. I again called that 198 complaint hotline, but the Tata Docomo peoples intelligently avoid my call by saying that all their representatives are busy and I should mail to [protected]@tatadocomo.com to register my complaints.
The point is, Docomo is cheating me and deducting more money than what they are promised at the time of recharge.
Herewith I had attached the screenshots of your website screens, which showing the tariff details for customers during the time of online recharge.
So, I request the customer care staffs of Tata Docomo to consider my issue and provide me the tariff of what they are actually promised at the time of recharge. That is, Local On-Net mobile calls free from 10pm to 6pm and 1p/6 sec from 6pm to 10pm. Validity: 30 Days
Please do the needful in higher priority, because I will definitely suffer till you do the resolution to my issue.
Thanking You
