Trai — tata docomo & idea

I have tata docomo prepaid sim which i have requested for porting in idea in the month of may 2017, but the location where i stay tata docomo network is not available. I was been told by idea that porting will be done within 7 days but still after & day idea sim was not working.

After complaining to idea regarding this idea say porting from docomo to idea porting was done on 20/05/2017 & sim is inactive from idea & it has been send back to tata docomo

Then after complaining to tata docomo regarding this issue it says that sim is converted to idea

Both tata docomo & idea are not giving any information regarding how to activate that sim
