Not the band, the ISP.
I currently pay for mine through Freedom to Surf but my landline calls are with TT.
They're offering a deal which includes "free" broadband and would save me about £15 a month. Sounds very tempting.
I don't want to swap and find out the service is shit though.
Any experience?

Just bumping in case there is someone on here that's used them.
They're calling back tomorrow night.
Online reviews suggest they're pretty bad overall but any additional input will be gratefully received.
Yup, i'm on Talk Talk
I think it's probably the same deal you're on about, really good service, downloads are limited to about 40Gb a month. Definitely recommend using them.
Thanks.
Lots of the reviews suggest that the speeds aren't great.
Mine's been really good and consistent.
Only trouble i've had with them is that my router broke, phoned them up and they sent me a new one in a couple of days!
My broadbands run by a group of giant birds!

Do NOT go anywhere near TalkTalk
Can't explain now as I have to go but just don't. They are absolute fuckboxes.
