I have been using ABC Broadband for past one and half year.Its a costly ISP compared to local providers but there is no hassle regarding the cable or switches being stolen on buildings like cable net.The only problem being that if the AP has a problem , it takes time for resolution.
The nearby access point had no battery backup for at least 4-5 months now and they closed all the complaints without any resolution.
My experience has been a good one and I hope it lasts till the end...
Also, the billing system is very poor.
