Address:	110006
Website:	87634230 this is our complaint no.

This is my worst experience with airtel last month i got airtel broad band connection on 25/8/17 install in our office. I choose 1099rs (Tax extra), 90gb, 40mbps speed.
Yesterday i hv paid 1052 bill but still i got 6.59 speed. I had complaint in airtel. But engineer said airtel provide on that speed.
If i am not getting 40mps speed then i discontinue with airtel. I'll never ever connection with airtel.
