Reliance Jio Infocomm — jio centre

Address:

Bangalore, Karnataka, 560090

On 18.01.2019 i had been to jio centre which is located near ayyappa temple to get duplicate jio sim as i had lost my mobile. There jio staff told me to get 4g mobile for getting duplicate sim. Evening when i went there with 4g mobile, in which already one airtel 4g sim is used and other slot was empty. I asked to activate jio number in other slot. But those people said, if 4g 2 sums are inserted in one mobile, mobile will be in problem and they are not responsible for that. Staff was very rude in his behaviour with customers, he is not at all treating customers in a good manner. What is his intention behind asking for a mobile before giving sim to me. Is 2 sims of 4g really causes problem to mobile.
