Airtel company not able to provide 4G /3g services in hiranandani, Hostel no. 12, 5 of IIT Bombay, Powai area from last 1 week.
Mobile will show 3G, H, LTE near network signal logo but speed will be less then 1kb/hour. I have paid 399 for this pack and Airtel company won't able to solve this problem from last 1 week. I have complained in the customer care number, apart from sorry and apology, nothing they can do. they are sitting there to tell the existing data, not able to solve the problem neither escalate the problem to extreme level. they duty is to take feedback and throw it in the dustbin because after so many sorry and apology, I am still facing the same problem.
if Airtel company not capable enough to provide a basis internet services in powai and Hiranandani area then please refund my money back.
