Airtel — slowest network

I m getting huge network problem complaint a lot time no solution till now. Full day i use to change my network 2g then 3g then 4g then again 3g some how it works for few minute further it again comes to emergency call only, no service. Its too irritating at all. Even outcoming calls are stopped almost it comes in inbox by miss call alert. It can be adjusted for few days or week also but not month after that i m facing it from 4-5 months. Complaint approx 10-15 time on care, online both medium but there is no solution. There last words are wait for 72 hrs it will b working but there 72 hrs doesn't over just get fed up of this network after the over of this recharge going to port my number very soon.
This is the only solution.
Very slowest network i have ever faced.
