Trai — idea 4g services not available on certain 4g handsets

Address:

Mumbai City, Maharashtra

Hi, i have ported my no. [protected] from reliance to idea as they offered me a plan with 1gb 4g data per day and unlimited calling. However, what i actually got was total 2g 1gb data valid till 16/10/2017. On inquiring with the customer care, it was told that idea don't provide service to mi redmi 4 handsets and i have to change the handset or move from mumbai to any other part of maharashtra in order to enjoy 4g services. I asked him to provide me with the complaint no. And he refused to take complaint and provide any complaint no..
I think customers are not aware on what frequency idea provide 4g services and being 4g handset they opt for idea services. Is it not ideas duty to inform customers or publish publicly that there 4g services are not available on certain 4g enabled handsets?
Please look into it and save customers from idea.

Thanks and regards,
