Reliance Jio — Misusing

Address:

400057

I had generate code from my 4g mobile and go to the reliance digitl store . They said that your code is already redeemed.

For this i had write an emai also but no response. After 3 days i call jio customer care they said the same reason that your phone imie number is used now u r not able to generate a code in short u will not get jio sim.

How can its possible if the sim is regitered to the phone imie number than how it can be used on other phone and how they issued the sim. It can be miss used by anyone.
