penno

Need a little help, i have put myself on Yell.com which cost me nothing and also got an email saying i will appear in the yellow pages directory from August.
Now i have had a bloke on the phone waffling on about advertising in the Yellow pages, was busy so just said send me some info. Basically now got a pack with things for me to sign at a cost of £126 a year! thought it was free. Is this bloke just trying to sell me a bigger spaced advert?
Will i still appear for free if i dont sign this paperwork?
Or is it worth signing it if i get a larger space?
thx
Mat
