Airtel — Increment in plan price but network issues are still unresolved

Company is continuously increasing the price of plan like Rs 49 plan is discontinued now Rs 79 plan is increased to Rs99 but there is still so many issues related to network. I'm very disappointed with all this. These are extremely expensive for many of the middle class persons and as they are limited for 22 or 28 days that means we have to recharge the number for every month and if the talktime is not used then it's wasted. Which makes it more uncomfortable and expensive. So stop increasing price and start increasing validity and quality of the product otherwise I've no choice rather than porting the number or discontinue the use of your network.
