My experience; around 24th sep, my broadband stopped working. I lodged a complaint and after a few hours got a call from a lady that I have exceeded the limit and the speeds will be low till month end. When I told her my connection is not working, she was surprised, offered to reset and asked me to check and she held the line for confirmation. The connection was restored immediately. I think the software is still buggy, and I did not find a significant reduction in speed from 4 mbps for the balance 5 days.
