I regularly use 1899 to dial France 1p/min. On Feb17th when I tried to call I was surprised that the tariff message said 3p/min. I hung up looked at the website and it stated quite clearly that the rate was 1p/min.I then dialled 1899, one of the options was to find out the rates for the number you are trying to call, I put in my number and the answer came back that it would be 1p/min.,so  made the call, tariff message said 3p and indeed that was what I was charged.Several emails later I get the following message  the rate quoted on the tariff message is what counts and todays email is as follows

So p[lease be warned and beware, since 1866 is apparently run by the same organisation, always opt for the tariff message and forget about the published rates.

Yes always opt for the message.

18866 and 1899 do say on their website the cost will be that of the announcement, and that it supersedes the cost displayed on their website.
