3 Months ago I left Vodafone after a six month ordeal of them getting my billing wrong in their favour every time.
Now with Flip and I must say that apart from ONE BIG ISSUE they are far and away the best ISP I have ever had.
They actually seem to care for their customers and my ADSL speed is up from 10 to 12 Mbs even the uploads are a bit faster.
Billing has not been an issue with plenty of feedback as to what they are actually going to charge you - they are a complete reversal of Vodafone in that respect. Only Flip debits your credit card, whereas Vodafone bill you.
I'd prefer Flip have online billing allowing bank d/c but thats a minor niggle.
The problem I have and it wont get sorted is that they use CGNAT so your sharing an IP address with others. The downside is that the IP address changes as often as every 10 seconds. Normally this would not be an issue, but if you deal with sites like I do as a web developer, its a problem; some websites continually monitor the incoming IP to check its same and if it changes you get logged out.The only method to sort it is by using a static VPN, as Flip have told me they cannot (or will not) do anything about it.
If you are in the market for general household internet use I'd recommend Flip.
FLIP 4 STAR RATING OUT OF 5 * * * * (a 5 if CGNAT was changed)
