Thank you Chris. As you can see, I first made TalkTalk support aware of this issue 19 days ago. Typically it can take weeks/months for problems to be fixed so the more users who post problems rather than just leave it or put up with it, the better.
This afternoon I sent two emails to a gmail address - neither has arrived. I also sent two emails to an outlook address - only one has arrived. There is definitely still a problem. Very disappointing. Come on TalkTalk.
