This is what is written in my package. This is why I find it strange as its conflicting.
@kkkk I'd go with whats on page 3 of the bill and say you're on the Unlimited Weekend calling plan but we'd like to take a look from our side. Please can use the 'click here to contact the mods' link in my forum profile to send in your details. You can find the link by clicking on my username.
Have you actually tested whether you are charged for a weekday evening call?
The issue is being looked in to, it appears to be an error in the standard script of bills issued..
