I have been using Neuf.fr myself at home now for 6 months and am so impressed that I have to suggest it to all my clients and friends here in France.

Both in the UK and now France there are a lot of businesses using premium phone lines for their customer services telephone number. This is quite out of order if you need to call customer services because they have let you down somehow and then you have to pay for the call.

Luckily there are usually normal geographic numbers that you can call instead of the premium rate lines and still get the same service.
In the UK check out SayNoTo0870.com
If France have a look at GeoNumbers.com
