I have been with Firefly for almost 5 years, and up until a year ago they were very good, and I had a fast reliable connection.

Recently however, the speed dropped so that now I only get 0.5 Mb/s rather than the 8 Mb/s that I pay for. When I contacted the helpdesk, they were rude and unhelpful, despite raising numerous tickets, and the problem still has not been resolved.

Furthermore, I am paying £25 per month, which is very expensive, especially when you also consider that Firefly support is 9-5 during on weekdays only.

In the end, I have decided that enough is enough, and am moving to O2.

Update

I have just been set up with O2, which costs less than £10 per month, and I am now getting over 12 Mb/s
