Thanks for your swift response. Very helpful. Why didn't the BT person I asked about getting a transcript of a Chat converversation tell me that? Infact was inistent on giving me info I was 99.99% wrong. Like I had to make a SAR by emailing email@example.com. Do you happen to know anything about that.
It gets pinged back to say it doesn't exist!
The question arose because I had just been on CHAT and the person had abruptly disappeared and I was shown a Thank You message and a survey to fill in. So I did. Yippee. Then to my astonishment the original chat reappeared complete with reply boxes. So I scrolled through it taking screen shots of it all.
Firefox: I include this here because it may be of interest to other users who are searching for it here. Apparently Firefox regard Chat as a website or webpage. If they don't know about it they record what's on it send it to you separately from your normal window.
Anks again for your help.
