just called sit up ltd(bid tv etc)who use the dreaded 0870 number,the recorded message says the call was charged at national rate,it was 6 minutes of listening to annoying music before anyone answered,luckily for me i connected via their switchboard so this call was free as im on a price plan,had i connected via the 0870 number it would have cost me 48p before my problems were even mentioned+the 5p connection charge ntl charge for ngn calls+the rest of the duration of my call which lasted a further 10 minutes 80p,a grand total of £1.33 on my phone bill for connecting to one of these annoying rip off numbers,instead my call was free as i used a geo number.
Another example of a large company cashing in on the 0870 rip off,and telling loyal customers that they are being charged at national rate,thanks for sites like this to help save us from the big 0870 rip off.

I think he ment he connected via "sit up tv" 020 number.
