I am using Tata Docomo prepaid sim card since from last year. In beginning, it works best as by providing low call rates, special internet offers etc.
Now I am having following problems with it: -
1-While using Internet, if you consume 100KB they will deduct 150KB. This way they are cheating the customers.
2-All call ratea are higher than that of beginning.
3-They sending me a message regularly with some useless offers, even I called them to activate DND, but still my sms memory is filling regularly with their Nonsense sms.
