Idea Cellular — Unable to get 4G service

Address:

441111

I brought new idea card ([protected]) 4g sim from idea stores, poonam chambers, sadar, nagpur on 29th may. I recharged it with rs. 446/- which gives 4g 1gb per day for 70 days. But i am getting 3g speed. Inspite of complaining many times to idea problem is not solved. Idea customer care executive is saying there is some technical problem. But they are not resolving it.
