Jio — advance payment fraud

Address:

560043

I am using jio communication sim and i have made advance payment recharge as per jio offer. But my internet is not working and they are saying it will be fixed after 90 days. I have already paid for 90 days plan and by the time it will be fixed my plan will be over. I have paid 399 for 3 months. I want company to refund my money as they couldn't provide promised 4g services. I am. Not getting signals to make calls also.
