Address:

Hi airtel,

I am not getting signals on my phone for airtel when i am inside my office. Due to which i am facing lots of difficulties. I have contacted customer care and they have raised a complain, but it has not resolved. Since i have poted vodafone to airtel due to connectivity issue in my home, but now i am facing same situation in my office with airtel. Also, i am unable to port it to other network, as according to try 90 days window is required t port. Please help me on urgent basis, as i am paying so i need to get my queries resolved.
