Airtel — data is very slow

My data is very slow and intermittent. Although i have ~190gb of data left in my plan. I tried checking on the airtel app and after checking the network connection, it says there's network outage in my area and the problem will be resolved in 4 hours. I've been getting the same message for the last 6 days. There is no option to call and talk to the customer care representative any more. This is really pathetic. Firstly, the net stops working. Then the tools they have made for checking have this prefed answer of the problem will be resolved in 4 hours. And the customer care calling option has also been disabled leaving no way for the customer to complain. Simply pathetic service.
