Airtel — poor connection, voice cracking & almost no internet connection

Address:

Mumbai City, Maharashtra

I have a poor connection from airtel. I had raised a complaint to airtel but till now there has been no improvement. On the contrary the problem has aggravated and i have been informed that my cell phone is unreachable at times. This is impacting my work. I have complained many times but problem still persisting, instead of solving my issues, advised to send a sms at 515 for internet connectivity problem, no improvement till today.
