Idea Cellular — about internet connection

I have recharged my idea sim on 22/07/2017 for my number [protected] for 399. As i had following offers by recharging 399 for my number i. E, all local and std free calls, 1gb 4g or 2g internet per day for 84days. It was working normal till today afternoon i. E, 29/07/2017. Now my sim network is working in 2g network and has no speed at all. I have called customer care for 4 times and they couldn't help me. I followed all the instructions given by them and they were all useless. I kindly request you to work on this problem and make 4g speed connection available for my sim. If that's not possible deduct the money for all services used till the date from 22/07/2017 and refund my amount. I had jumped from jio network to idea trusting on the network, but never expected such poor service.
