Not sure if this is the right place to put it, but when I sign up to something new, I look for a support or forum to see what others are saying.
At the bottom of the Sign Up – Yayzi Broadband pages there is a link to the forum, but it is pointing to hob.yayzi.co.uk whereas this forum is talk.yayzi.co.uk
I also found the same wrong link at the bottom of the contract page when viewing your contract.
I’ve now signed up and got my install date, cant wait to get my first fibre broadband.
