Which pipex deal do you guys have and how much is it per month?

Cheapest is £14.99 but its capped to 1gig? Do you have the £23.99 package with no cap? do you have inclusive phone calls? how do you use them? do you have to dial extra numbers in front of your number to call so that bt dont charge?

I didnt really wanna go above £18/£20 because houses are expensive enough i can see
