Airtel — data plan not assisting correctly

Address:

500045

I selected 599 postpaid plan for hotspot which is 4gb daily and additional of 8gb but in real they provided 12gb of data for some time and slow down the speed to 2g which is not connecting and working now. Very worst network but promotions saying very fast network. I tried so many times to customer care also and every one is singing the same song. No one is not trying to resolve the issue and resulting i don't have internet from saturday. It's all fake advertising and attracting the customers
