Although no problems with the sign up process, I was about to jump on TCB as they were only showing as £38 cashback even though I signed up on Sunday when it was still £101.

After reading your post that, reminded to shout at TCB and after looking it seems that everything is sorted as it's showing the correct amount now!

Roll on 10th June ....

I usually use TCB but I missed out on their deal due to my dithering.
Hope to hear how your install goes on the 10th
