Address:

Odisha

respected sir, i am Asit Kumar Panigrahi from Sonepur, Orissa. My docomo no. is [protected]. on 20th november at 12.36 pm i had a call from [protected] which used to be customer cares number. i rejected the call because i was very busy then. then suddenly in a few minutes a had two sms from 543211. the two sms are as follows. 1st one is ."thank you for subscribing to call me tunes.Rs0 has been charged for 5 days" and the 2nd one is "thank you for downloading tu jab jab mujhko pukare.Rs.15 is charged." so i don't understand that how this call me tune activated automatically. . when i called to customer care the representative without proper inquiry about the matter as well as not going through the duration of the call i got, he told me that you have activated this service yourself. he further told me that write DATA and send it to 121 to get your data usage information. when i sent the similar to 121 then i got the reply sms as "Dear customer, You have no data usage till date." then i tried to connect to the care for several times but each time it got disconnected. i further tried to connect them from another number but again without proper query they told i have done everything. my complain is that for a student 15 rupees on phone is not a joke. you'll be astonished to know that" i'll never avail this service if it'll supplied free of cost". so sir my complain that when i've not done all these how someone can held me responsible for the same. so please help me please make a proper investigation i've still that msgs and call logs which i can supply if i may be asked. i want my balance back so sir plz help me.
