I am from Pune (Sahakarnager). From a 4 Moths I dont have any issue from ABC Broadband other than Customer care service. Before getting ABC Broadband Broadband check following things.
1) ABC Broadband server and your home distance should be under 300 m to 400 m
2) ABC Broadband server should be visible by naked eye.
3)Very IMP Single Strength should be above 65% that is 4 candles LED should be blinking.
If you have above criteria then you will dare to get ABC Broadband and recently their connectivity and speed improve in Pune.
But customer care services is not good as other ISP.
