if the FTTP TEAM number is busy then you get redirected to CS. you just need to keep trying FTTP
Just to add to this.
I've tried a third party router and get exactly the same issue so must be either an ONT issue or a line issue
All up to decent speeds now.
Ran a speedtest last night on fast.com and got 1.2GBPS!
So what's happened in the last 4 days?
Would have been handy to get an update as to what the issue was!
