Dear all,
I made an inquiry to one world teleservices regarding international sim, as per this company oral information, i send my passport copy, international air ticket copy, and front page of my sbi credit card copy through my mail.
The next day i received the international sim, but i am not received any information regarding my questions, so i decided and send back the sim immediately by the same courier, once i send back the sim i got some information regarding, but i said its too late i already send.
Some days after i check my sbi card online, there is a application charge for this sim, immediately i inform sbi, the charges or back, next month they raised the charge for the international sim rent, i inform to sbi, they refused to delete charge and they said me that my card is used (I never used my card) at this time, and they send me the international sim request application copy.
I am not received any application, also i am not sign in this application, the one world tele service copy my sing from my passport copy and paste it in the application, but i do not know without swiping my card without my cvv or otp, how this transaction is valid by sbi?
All my question there is no proper answer, now i loss nearly 1000 rupees.
Could you please help me to fight for truth.
Regards
